Hey friends,
I appeared for the sap placement exam. It consisted of 5 sections:Total time given was 1 hr and 30 minutes. There was no negative marking.
1. Aptitude:- (10 questions) 1 mark each question.
- Question were from time and work (e.g.: if 5 women and 6 men can complete a task in 4 days. 6
women and 7 men do the same in 8 days then in how many days 1 men and 1 women will do the task.? )
- Questions based on directions(e.g:- if one moves 5 km in north direction then moves 4 km in left
direction and so on then what is the total distance that he takes and what is his direction now..)
note: there were around 5- 6 questions of the same type as mentioned above.
- 1 Question on probability.
- Q. If there are 4 chairs. among 6 men and 4 women , 2 men and 2 women are to be seated on the
chairs then what is the probability of them to be seated.
2. Logical reasoning:- (10 questions).
- Most of the questions were on blood relations and were not that easy for me.
- If ganga is coded as "qpstv"(I don't remember code) then what is the code for watch? (there were
two such questions).
3. Verbal:- (10 questions).
- An essay of not more than 300 words had to be written and it carried 10 marks. my topic was
competitive exams in india. i wrote around 250 words.
- Identify error in sentence.
- Jumbled sentences.
- Synonyms.
4. Technical:-(10 questions).
- Very basic and simple questions from c and dbms.
- What ends the string. ans is null
- Find the error.
5. Coding section:-(1 program).
1 program was given to write and it carried 20 marks. If the program is successfully then only 20 marks
will be awarded else 0 is given.
My question was to reverse a string. There were some warnings in the program. So I don't think I will get
marks for that the result is still to come. Hoping for the best.

SAP LABS PAPER & INTERVIEW - 10 OCT 2007 - BANGALORE
Rated : +224 , -29
Hi Friends
I am JAMEER PATAN from Andhra Pradesh. I had selected for SAP LABS on Oct 10 2007 near White
Field., Bangalore. This is my 43rd company. Now i want to share my feeling with u all now i am
explaining about SAP.
Pattern:
30 questions - time: 1 hour
Subjects: basic aptitude, C, DBMS 25 were objective remaining with no options
1.about rain problem in a tour ans:18 days
2.odd man out: ans:d
3.a car travels at a certain distance and came back similar to a infosys puzzle ans:45kmph
4.a clock 6 times per min how many times it strikes 12 sec ans:66 sec
5.how one lakh can be represented with out using zeros
6. C question ans:mmmm
aaaaa
nnnnn
dddd
7.printf("%d",3.14*6.25*6.25).... question regarding to macros
8.one C question ans is 5 prints infinite times
9.normalization this is one of ans for dbms question
10.more than one attributes this is one of ans for dbms question
11. 2 degree is ans for aptitude bit
12.353 is one of the answer for aptitude bit
13.0 is one of aptitude bit answer
Sorry friends I remem this questions only bcoz I am from ECE background so I dont know DBMS. all
questions from DBMS were select * from users.... etc for cse students it is very easier to crack. the cut off
is nearly 18 marks. with in 45 minutes they declared the result. I am one of the person who cleared the
written. I didnt feel happy bcoz this is my 35th written clearing
Technical Interview:
they focus on project, c, sql, puzzles.. if u prepare infosys puzzles then u can answer any puzzles. In C
they asked to swap two numbers with out using third variable, reverse of a string using pointers, small
small programs aked. they asked project deeply.
In DBMS they asked normalization, foreign keys etc,
Basics in C++
then they declared the result with in 20 min i.e i cleared technical this time also i didnt happy bcoz this is
my 18 technical interview clearance.
HR:
they told abt job profile i.e it is a contract basis for one year and asked some basic hr ques like tell me abt
urself, strengths, weakness. I am 2007 passed out even thoug it is a contract basis i joined SAP on 29 now
I am in Sap for one year. I advice u not to loose hope if we lost one thing means there is another thing
waiting for which is better than lost one. So be confident, do hard work, pray god there will be definitely
one day for every person.
Hi Friends
paper consisted of 2 sections:
1-logical (30 q's-30min)
2-technical(30 q's-30 min)
Logical part (including apt q's)
1. two questions based on blood relations
2. some questions based on finding who is who-eg: 3 three persons namely mahesh,tapan,farhan who r
director,producer,actor not respectively are staying together and some relations will be given using that
we should find out who is who.
3. few basic apt q's from agarwal book(not so tough).
4. most of the q's on mathematical expressionsfor eg:+ indicates /,* indicates -,- indicates+,/ indicates *
evaluate the exp:2/3*12+2-3 some thing like that.
5. similar to above q,4 exp will be given and we should chech out which exp is correct,after replacing the
respective symbols.
6. two stmts will be given n need to check whether stmt 1 is enough or stmt 2 is enough,or both -like
that.(4 to 5 q's of this type).
here for this paper time mgmt is very very impt.
Technical part ( C)
1. few q's on finding the o/p.
2. few on identifying the correct algm(bubble sort,selection sort etc).
3. study pointers chapter very well coz most of the q's will be from that.
4. some q's on choosing the correct function to be inserted from the given options.
5. few numbers will be given n asked to arrange those using bubble sort or selection sort or some thing
like that.
all the best, Bharathi
Hi Friends
The paper was set by merittrac. There were 2 sections.
1st section had general aptitude questions and the 2nd section had ques based on C and data
structures.
Section 1: 30 ques :30 mins (time was not sufficient)
I remember only a few questions.

of joining she gets Rs.15,000 and after 10 years she gets Rs.18000. wat is her salary when she joined?
2. There were few elephants and an equal number of mahouts.Half of the mahouts were sitting on the
elephants and half were walking.Totally there was 84 legs, hw many elephants were there?
3. some data sufficiency ques
4. one question based on venn diagram
5. Usual merittrac pattern,some 7 ques like, if * stands +,- stands for /,+ stands for * and / stands for ,then 24+7-6*8/2=?
Section 2:

Hi Friends
This paper was quite different from the previously stated ones.
2 sections only. 30 mins each. No negative marking. (although the page said -0.25... i was informed by
the guys when i was on the 2nd section!!!!!!)
All questions on a single scroll down page.
No RDBMS!!!!
Once the first 30 mins are over u ca't go back to the previous section.
Section 1 : Logical Reasoning (only 2-3 questions on %age, etc very simple)
30 questions/30 Mins.
1. (easy) ABCDEFG are lessons... they need to be taught according to some 5-6 given conditions ....
a) Which is the correct order?
b)Which lesson is a must if only 4 need to be taught.
2. (easy) Two politicians...winner % votes recd of total votes...?
3. Batsman...average runs in first innings... (lengthy question).
3 or 4 questions on Sufficiency.. (a lil tricky)
5 questions on replace the mathematical operators and evaluate... (Do we use BODMAS here???)
Basically all the questions very easy... i f u preapred for CAT even for just 1 month u'd get thru. But the
questions were very much not solvable in 30 mins..
Section 2 : Technical (Algorithms/GraphTheory/C)
30 questions/30 mins
2-3 code snippets were given.. had to choose the correct algo complexity (big O)
1 code completion snippet on DFS (depth first search) (very easy)
1 question where graph was drawn.. had to choose the shortest path!! (childs play!!!)
Q) const can be used with a)array b)identifirer c)array argument d)all
Q) Find the incorrect statement : ans : dynamic allocation is done at compile time. (false)
Q)same ques repeated twice " what does adjacency matrix show?"
Q) 2-3 questions on prefix/postfix/infix conversion. (easy)
I finished the second section with 4 mins to spare. It was very easy. But the first was too lengthy and
frustrating...besides they din tell me soon enough that there was no -ve marking.
All the Best

hi Friends
The Sap Labs is not directly conducting the exam. It handed over this task to a consultansy named
CAREER PLANS. The short listed candidates will be taken interview at sap labs. This is what i know.
Now coming to the pattern of exam.
IT consisted of 4 sections and we have to show adequate competeance in each section. No negative
marking. And the 4 sections completely comprise of 75 q's we have time limit of 1hr. Here what matters
is time.
The q's are really easy to answer.
The 4 sections are as follows
1. LOGICAL REASONING-------------- 20 Q'S
2. DATA INTERPRETATION AND DATA SUFFICIENCY---------------- 20 Q'S
3. MATHEMATICAL REASONING--------------------- 20 Q'S
4.READING COMPREHENSION AND VERBAL ABILITY--------------15 Q'S
They said that the short listed candidates will be intimated thru a mail or a call.
ALL THE BEST!!!!!!!!!!!!!!!!!
The pattern is as follows;
CAT pattern:
20 questions analogy : Questions on KYA KYA island 3, one says lies other says true questions
II Data Interpretion 20 questions:
PIE Chart and Bar graphs 10 each total 20 (attempt them very easy 5 mins)
III quants: simple preapre the basics time speed, ages father and relations questions. relation questions
(like there r 8 people 4 r males 4 r females abcdefgh..one is father
questions were like how many males r there? females?
what is the telation of a n c?..etc
IV english comprerhension 2 passages
One was abt renewable resources pertrlouem saving indian economy searching 4 alternate resources of
energy solar cooker.........like that
Read the questions and answer them directly no need to read the entire passages both of them.
Basic grammer, meanings (sorry guys words I am unable 2 recollect)
Preapre model papers 4rm GRE and time MBA matreial was helpful.
Interview pattern:
Hr type : 2 puzzles, talk abt some topic 4 2 minutes, talk abt ur favorate subject 4 1min, ur projects and
what u did and overall idea..., puzzle was
1) there is a square of 3 rows n columns arrange numbers 1 to 9 such that sum is same (expalin logic)
2) tis tac game...who chance is next??
Interview is easy just be kool headed and communicate properly. Afetr Interview there will be an PAT
(personal assessment test) simple
There was 3 section in written test
1. Verbal
2. Reasoning
3. Reneral aptitude
(25q-20m)
(30q-30m)
(30q-30m)
1st section some preposition, meaning etc.
2. testing similarity like
1) a)aaccvfgg
2) a)8812.4567
b)aaccvfg
b)8812.4523
c)accvfggg
c)8812.4321
d)aaccvfgg
d)8821.3421
questions like reading passage and answering there was 2 passages and 5 questions each
3. general aptitude contains basic maths questions like
1. person A starts at 9 am from x to y, rate of 4km at the same time person B starts from y to x, rate of
3km. at what time they will meet? x to y distance 27
2. $ for 0, ! for 1
5 sub questions to represent using $ and ! like represent 480 using above foramt (first convert to Bin )
3. there was questions that should solve using venn-diagrams (Refer GRE u will get sample questions
above mentioned)
Peace of mind is attained not by ignoring problems, but by solving them.
Hi Friends
SAP written test is on line test conducted by merittrac.
it contains 3 sections.
1. Aptitude: questions based on logical reasoning, easy but time killing.
15 ques-----------------20 min
2. RDBMS: questions based on codd's rules, normalization, sql queries,
little bit tough to my knowledge
20 ques.................20min
3. Optional(C/C++/Java): mine is C, easy, concentrate on memory allocation, pointers.
20ques...................20min
Paper: SAP Interview Pattern & Interview Tips
Interview Pattern:
Technical Interview: Discussion on the written paper. How did u solved the problem? explain him about
that. small discussion on yr project for a while. simple technical questions related to project. simple
language question : Collections in java.. types of joins in SQL. if u want to ask something about sapient
etc?
Hint: Ask something good. eg kind of projects they are doing.. processes they follow .. how do they
capture the requirements etc.
Business Interview 1: Hr interview.. behavioral questions.. how will u react in some conditions.. how
how did u reacted..
1) Give an example when your boss is not agreed with u. what did u do?
2) Give an example when u had a clash with your peer. what did u do?

properly ) what did u do?
4) Give an example when u faced some stressful situation. what did u do?
5) Did u make some decision of your own to carry out something. and suggested this to yr boss and your
boss agreed?
Hint : Ask some good question. like how open the environment is? is a junior person part of design??
what is the responsibility of a member for the proper working of project?
Business Interview 2: This was more of type 2 only. but they will tell about sapient. and u may ask as
many question as u want. now u can again ask the same question asked in previous 2 interviews.
SAP BW Important Interview Questions Paper- Part - 4
Q) I would like to display the date the data was uploaded on the report. Usually, we load the
transactional data nightly. Is there any easy way to include this information on the report for users? So
that they know the validity of the report.
A) If I understand your requirement correctly, you want to display the date on which data was loaded
into the data target from which the report is being executed. If it is so, configure your workbook to
display the text elements in the report. This displays the relevance of data field, which is the date
on which the data load has taken place.
Q) Can we filter the fields at Transfer Structure?
Q) Can we load data directly into infoobject with out extraction is it possible.
Yes. We can copy from other infoobject if it is same. We load data from PSA if it is already in PSA.
Q) HOW MANY DAYS CAN WE KEEP THE DATA IN PSA, IF WE R SHEDULED DAILY, WEEKLY AND
MONTHLY.
a) We can set the time.
Q) HOW CAN U GET THE DATA FROM CLIENT IF U R WORKING ON OFFSHORE PROJECTS. THROUGH
WHICH NETWORK.
a) VPN.Virtual Private Network, VPN is nothing but one sort of network where we can connect to the
client systems sitting in offshore through RAS (Remote access server).
Q) HOW CAN U ANALIZE THE PROJECT AT FIRST?
Prepare Project Plan and Environment
Define Project Management Standards and
Procedures
Define Implementation Standards and Procedures
Testing & Go-live + supporting.
Q) THERE is one ODS AND 4 INFOCUBES. WE SEND DATA AT TIME TO ALL CUBES IF ONE CUBE GOT LOCK
ERROR. HOW CAN U RECTIFY THE ERROR?
Go to TCode sm66 then see which one is locked select that pid from there and goto sm12
TCode then unlock it this is happened when lock errors are occurred when u scheduled.
Q) Can anybody tell me how to add a navigational attribute in the BEx report in the rows?
A) Expand dimension under left side panel (that is infocube panel) select than navigational attributes
drag and drop under rows panel.
Q) IF ANY TRASACTION CODE LIKE SMPT OR STMT.
In current systems (BW 3.0B and R/3 4.6B) these Tcodes don't exist!
Q) WHAT IS TRANSACTIONAL CUBE?
A) Transactional InfoCubes differ from standard InfoCubes in that the former have an improved write
access performance level. Standard InfoCubes are technically optimized for read-only access and for a
comparatively small number of simultaneous accesses. Instead, the transactional InfoCube was
developed to meet the demands of SAP Strategic Enterprise Management (SEM), meaning that, data is
written to the InfoCube (possibly by several users at the same time) and re-read as soon as possible.
Standard Basic cubes are not suitable for this.
Q) Is there any way to delete cube contents within update rules from an ODS data source? The reason
for this would be to delete (or zero out) a cube record in an "Open Order" cube if the open order
quantity was 0.
I've tried using the 0recordmode but that doesn't work. Also, would it
be easier to write a program that would be run after the load and delete
the records with a zero open qty?
A) START routine for update rules u can write ABAP code.
A) Yap, you can do it. Create a start routine in Update rule.
It is not "Deleting cube contents with update rules" It is only possible to avoid that some content is
updated into the InfoCube using the start routine. Loop at all the records and delete the record that has
the condition. "If the open order quantity was 0" You have to think also in before and after images
in case of a delta upload. In that case you may delete the change record and keep the old and after the
change the wrong information.
Q) I am not able to access a node in hierarchy directly using variables for reports. When I am using
Tcode RSZV it is giving a message that it doesn't exist in BW 3.0 and it is embedded in BEx. Can any one
tell me the other options to get the same functionality in BEx?
A) Tcode RSZV is used in the earlier version of 3.0B only. From 3.0B onwards, it's possible in the Query
Designer (BEx) itself. Just right click on the InfoObject for which you want to use as variables and
precede further selecting variable type and processing types.
Q) Wondering how can I get the values, for an example, if I run a report for month range 01/2004 10/2004 then monthly value is actually divide by the number of months that I selected. Which variable
should I use?
Q) Why is it every time I switch from Info Provider to InfoObject or from one item to another while in
modeling I always get this message " Reading Data " or "constructing workbench" in it runs for
minutes.... anyway to stop this?
Q) Can any one give me info on how the BW delta works also would like to know about 'before image
and after image' am currently in a BW project and have to write start routines for delta load.
Q) I am very new to BW. I would like to clarify a doubt regarding Delta extractor. If I am correct, by
using delta extractors the data that has already been scheduled will not be uploaded again. Say for a
specific scenario, Sales. Now I have uploaded all the sales order created till yesterday into the
cube. Now say I make changes to any of the open record, which was already uploaded. Now what
happens when I schedule it again? Will the same record be uploaded again with the changes or will the
changes get affected to the previous record.
A)?
Q) In BW we need to write abap routines. I wish to know when and what type of abap routines we got
to write. Also, are these routines written in update rules? I will be glad, if this is clarified with real-time
scenarios and few examples?
A) Over here we write our routines in the start routines in the update rules or in the transfer structure
(you can choose between writing them in the start routines or directly behind the different
characteristics. In the transfer structure you just click on the yellow triangle behind a characteristic
and choose "routine". In the update rules you can choose "start routine" or click on the triangle with
the green square behind an individual characteristic. Usually we only use start routine when it does not
concern one single characteristic (for example when you have to read the same table for 4
characteristics). I hope this helps.
We used ABAP Routines for example:
To convert to Uppercase (transfer structure)
To convert Values out of a third party tool with different keys into the same keys as our SAP System
uses (transfer structure)
To select only a part of the data for from an infosource updating the InfoCube (Start Routine) etc.
Q) What is ODS?
A) An ODS object acts as a storage location for consolidated and cleaned-up transaction data
(transaction data or master data, for example) on the document (atomic) level.
This data can be evaluated using a BEx query.
Standard ODS Object
Transactional ODS object:
The data is immediately available here for reporting. For implementation, compare with the
Transactional ODS Object.
A transactional ODS object differs from a standard ODS object in the way it prepares data. In a standard
ODS object, data is stored in different versions ((new) delta, active, (change log) modified), where as a
transactional ODS object contains the data in a single version. Therefore, data is stored in precisely the
same form in which it was written to the transactional ODS object by the application. In BW, you can
use a transaction ODS object as a data target for an analysis process.
The transactional ODS object is also required by diverse applications, such as SAP Strategic Enterprise
Management (SEM) for example, as well as other external applications.
Transactional ODS objects allow data to be available quickly. The data from this kind of ODS object is
accessed transactionally, that is, data is written to the ODS object (possibly by several users at the same
time) and reread as soon as possible.
It offers no replacement for the standard ODS object. Instead, an additional function displays those that
can be used for special applications.
The transactional ODS object simply consists of a table for active data. It retrieves its data from external
systems via fill- or delete- APIs. The loading process is not supported by the BW system. The advantage
to the way it is structured is that data is easy to access. They are made available for
reporting immediately after being loaded.
Q) What does InfoCube contains?
A) Each InfoCube has one FactTable & a maximum of 16 (13+3 system defined, time, unit & data packet)
dimensions.
Q) What does FACT Table contain?
A FactTable consists of KeyFigures.
Each Fact Table can contain a maximum of 233 key figures.
Dimension can contain up to 248 freely available characteristics.
Q) How many dimensions are in a CUBE?
A) 16 dimensions. (13 user defined & 3 system pre-defined [time, unit & data packet])
Q) What does SID Table contain?
SID keys linked with dimension table & master data tables (attributes, texts, hierarchies)
Q) What does ATTRIBUTE Table contain?
Master attribute data
Q) What does TEXT Table contain?
Master text data, short text, long text, medium text & language key if it is language dependent
Q) What does Hierarchy table contain?
Master hierarchy data
Q) What is the advantage of extended STAR Schema?
Q). Differences between STAR Schema & Extended Schema?
A) In STAR SCHEMA, A FACT Table in center, surrounded by dimensional tables and the dimension
tables contains of master data. In Extended Schema the dimension tables does not contain master data,
instead they are stored in Masterdata tables divided into attributes, text & hierarchy. These Masterdata
& dimensional tables are linked with each other with SID keys. Masterdata tables are independent of
Infocube & reusability in other InfoCubes.
Q) As to where in BW do you go to add a character like a ; # so that BW will accept it. This is transaction
data which loads fine in the PSA but not the data target.
A) Check transaction SPRO ---Then click the "Goggles"-Button => Business
Information Warehouse => Global Settings => 2nd point in the list. I
hope you can use my "Guide" (my BW is in german, so i don't know all the english descriptions).
Q) Does data packets exits even if you don't enter the master data, (when created)?
Q) When are Dimension ID's created?
A) When Transaction data is loaded into InfoCube.
Q) When are SID's generated?
A) When Master data loaded into Master Tables (Attr, Text, Hierarchies).
Q) How would we delete the data in ODS?
A) By request IDs, Selective deletion & change log entry deletion.

21. How do you transform Open Hub Data?
¢ Using BADI we can transform Open Hub Data according to the destination requirement.
22. What is ODS?
¢ Operational DataSource is used for detailed storage of data. We can overwrite data in the ODS. The
data is stored in transparent tables.
23. What are BW Statistics and what is its use?
¢ They are group of Business Content InfoCubes which are used to measure performance for Query and
Load Monitoring. It also shows the usage of aggregates, OLAP and Warehouse management.
24. What are the steps to extract data from R/3?
¢ Replicate DataSources
¢ Assign InfoSources
¢ Maintain Communication Structure and Transfer rules
¢ Create and InfoPackage
¢ Load Data
25. What are the delta options available when you load from flat file?
The 3 options for Delta Management with Flat Files:
o Full Upload
o New Status for Changed records (ODS Object only)
o Additive Delta (ODS Object & InfoCube)
Q) Under which menu path is the Test Workbench to be found, including in earlier Releases?
The menu path is: Tools - ABAP Workbench - Test - Test Workbench.
Q) I want to delete a BEx query that is in Production system through request. Is anyone aware about it?
A) Have you tried the RSZDELETE transaction?
Q) Errors while monitoring process chains.
A) During data loading. Apart from them, in process chains you add so many process types, for example
after loading data into Info Cube, you rollup data into aggregates, now this rolling up of data into
aggregates is a process type which you keep after the process type for loading data into Cube. This
rolling up into aggregates might fail.
Another one is after you load data into ODS, you activate ODS data (another process type) this might
also fail.
Q) In Monitor----- Details (Header/Status/Details) Ã Under Processing (data packet): Everything OK
à Context menu of Data Package 1 (1 Records): Everything OK ---- Simulate update. (Here we can debug
update rules or transfer rules.)
SM50 à Program/Mode à Program à Debugging & debug this work process.
Q) PSA Cleansing.
A) You know how to edit PSA. I don't think you can delete single records. You have to delete entire PSA
data for a request.
Q) Can we make a datasource to support delta.
A) If this is a custom (user-defined) datasource you can make the datasource delta enabled. While
creating datasource from RSO2, after entering datasource name and pressing create, in the next screen
there is one button at the top, which says generic delta. If you want more details about this there is a
chapter in Extraction book, it's in last pages u find out.
Generic delta services: Supports delta extraction for generic extractors according to:
Time stamp
Calendar day
Numeric pointer, such as document number & counter
Only one of these attributes can be set as a delta attribute.
Delta extraction is supported for all generic extractors, such as tables/views, SAP Query and function
modules
The delta queue (RSA7) allows you to monitor the current status of the delta attribute
Q) Workbooks, as a general rule, should be transported with the role.
Here are a couple of scenarios:
1. If both the workbook and its role have been previously transported, then the role does not need to
be part of the transport.
2. If the role exists in both dev and the target system but the workbook has never been transported,
and then you have a choice of transporting the role (recommended) or just the workbook. If only the
workbook is transported, then an additional step will have to be taken after import: Locate the
WorkbookID via Table RSRWBINDEXT (in Dev and verify the same exists in the target system)
and proceed to manually add it to the role in the target system via Transaction Code PFCG -- ALWAYS
use control c/control v copy/paste for manually adding!
3. If the role does not exist in the target system you should transport both the role and workbook. Keep
in mind that a workbook is an object unto itself and has no dependencies on other objects. Thus, you do
not receive an error message from the transport of 'just a workbook' -- even though it may not be
visible, it will exist (verified via Table RSRWBINDEXT).
Overall, as a general rule, you should transport roles with workbooks.
Q) How much time does it take to extract 1 million (10 lackhs) of records into an infocube?
A. This depends, if you have complex coding in update rules it will take longer time, or else it will take
less than 30 minutes.
Q) What are the five ASAP Methodologies?
A: Project plan, Business Blue print, Realization, Final preparation & Go-Live - support.
1. Project Preparation: In this phase, decision makers define clear project objectives and an efficient
decision making process ( i.e. Discussions with the client, like what are his needs and requirements
etc.). Project managers will be involved in this phase (I guess).
A Project Charter is issued and an implementation strategy is outlined in this phase.
2. Business Blueprint: It is a detailed documentation of your company's requirements. (i.e. what are the
objects we need to develop are modified depending on the client's requirements).
3. Realization: In this only, the implementation of the project takes place (development of objects etc)
and we are involved in the project from here only.
4. Final Preparation: Final preparation before going live i.e. testing, conducting pre-go-live, end user
training etc.
End user training is given that is in the client site you train them how to work with the new
environment, as they are new to the technology.
5. Go-Live & support: The project has gone live and it is into production. The Project team will be
supporting the end users.
Q) What is landscape of R/3 & what is landscape of BW. Landscape of R/3 not sure.
Then Landscape of b/w: u have the development system, testing system, production system
Development system: All the implementation part is done in this sys. (I.e., Analysis of objects
developing, modification etc) and from here the objects are transported to the testing system, but
before transporting an initial test known as Unit testing (testing of objects) is done in the development
sys.
Testing/Quality system: quality check is done in this system and integration testing is done.
Production system: All the extraction part takes place in this sys.
Q) How do you measure the size of infocube?
A: In no of records.
Q). Difference between infocube and ODS?
A: Infocube is structured as star schema (extended) where a fact table is surrounded by different dim
table that are linked with DIM'ids. And the data wise, you will have aggregated data in the cubes. No
overwrite functionality
ODS is a flat structure (flat table) with no star schema concept and which will have granular data
(detailed level). Overwrite functionality.
Flat file datasources does not support 0recordmode in extraction.
x before, -after, n new, a add, d delete, r reverse
Q) Difference between display attributes and navigational attributes?
A: Display attribute is one, which is used only for display purpose in the report. Where as navigational
attribute is used for drilling down in the report. We don't need to maintain Navigational attribute in the
cube as a characteristic (that is the advantage) to drill down.
Q. SOME DATA IS UPLOADED TWICE INTO INFOCUBE. HOW TO CORRECT IT?
A: But how is it possible? If you load it manually twice, then you can delete it by requestID.
Q. CAN U ADD A NEW FIELD AT THE ODS LEVEL?
Sure you can. ODS is nothing but a table.
Q. CAN NUMBER OF DATASOURCES HAVE ONE INFOSOURCE?
A) Yes of course. For example, for loading text and hierarchies we use different data sources but the
same InfoSource.
Q. BRIEF THE DATAFLOW IN BW.
A) Data flows from transactional system to analytical system (BW). DataSources on the transactional
system needs to be replicated on BW side and attached to infosource and update rules respectively.
Q. CURRENCY CONVERSIONS CAN BE WRITTEN IN UPDATE RULES. WHY NOT IN TRANSFER RULES?
Q) WHAT IS PROCEDURE TO UPDATE DATA INTO DATA TARGETS?
FULL and DELTA.

SAP BW Important Interview Questions Paper- Part - 3
Q) AS WE USE Sbwnn, sbiw1, sbiw2 for delta update in LIS THEN WHAT IS THE PROCEDURE IN LOCOCKPIT?
No LIS in LO cockpit. We will have datasources and can be maintained (append fields). Refer white
paper on LO-Cockpit extractions.
Q) Why we delete the setup tables (LBWG) & fill them (OLI*BW)?
A) Initially we don't delete the setup tables but when we do change in extract structure we go for it. We
r changing the extract structure right, that means there are some newly added fields in that which r not
before. So to get the required data ( i.e.; the data which is required is taken and to avoid redundancy)
we delete n then fill the setup tables.
To refresh the statistical data. The extraction set up reads the dataset that you want to process such as,
customers orders with the tables like VBAK, VBAP) & fills the relevant communication structure with the
data. The data is stored in cluster tables from where it is read when the initialization is run. It
is important that during initialization phase, no one generates or modifies application data, at least
until the tables can be set up.
Q) SIGNIFICANCE of ODS?
It holds granular data (detailed level).
Q) WHERE THE PSA DATA IS STORED?
In PSA table.
Q) WHAT IS DATA SIZE?
The volume of data one data target holds (in no. of records)
Q) Different types of INFOCUBES.
Basic, Virtual (remote, sap remote and multi)
Virtual Cube is used for example, if you consider railways reservation all the information has to be
updated online. For designing the Virtual cube you have to write the function module that is linking to
table, Virtual cube it is like a the structure, when ever the table is updated the virtual cube will fetch
the data from table and display report Online... FYI.. you will get the information :
https://www.sdn.sap.com/sdn /index.sdn and search for Designing Virtual Cube and you will get a good
material designing the Function Module
Q) INFOSET QUERY.
Can be made of ODS's and Characteristic InfoObjects with masterdata.
Q) IF THERE ARE 2 DATASOURCES HOW MANY TRANSFER STRUCTURES ARE THERE.
In R/3 or in BW? 2 in R/3 and 2 in BW
Q) ROUTINES?
Exist in the InfoObject, transfer routines, update routines and start routine
Q) BRIEF SOME STRUCTURES USED IN BEX.
Rows and Columns, you can create structures.
Q) WHAT ARE THE DIFFERENT VARIABLES USED IN BEX?

Variable Types are
Manual entry /default value
Replacement path
SAP exit
Customer exit
Authorization
Q) HOW MANY LEVELS YOU CAN GO IN REPORTING?
You can drill down to any level by using Navigational attributes and jump targets.

Q) CAN CHARECTERSTIC INFOOBJECT CAN BE INFOPROVIDER.
Of course
Q) PROCEDURES OF REPORTING ON MULTICUBES
Refer help. What are you expecting? MultiCube works on Union condition
Q) EXPLAIN TRANPSORTATION OF OBJECTS?
Dev---Ã Q and Dev-------Ã P
Q) What types of partitioning are there for BW?
There are two Partitioning Performance aspects for BW (Cube & PSA)
Query Data Retrieval Performance Improvement:
Partitioning by (say) Date Range improves data retrieval by making best use of database [data range]
execution plans and indexes (of say Oracle database engine).
B) Transactional Load Partitioning Improvement:
Partitioning based on expected load volumes and data element sizes. Improves data loading into PSA
and Cubes by infopackages (Eg. without timeouts).
Q) How can I compare data in R/3 with data in a BW Cube after the daily delta loads? Are there any
standard procedures for checking them or matching the number of records?
A) You can go to R/3 TCode RSA3 and run the extractor. It will give you the number of records
extracted. Then go to BW Monitor to check the number of records in the PSA and check to see if it is the
same & also in the monitor header tab.
A) RSA3 is a simple extractor checker program that allows you to rule out extracts problems in R/3. It is
simple to use, but only really tells you if the extractor works. Since records that get updated into
Cubes/ODS structures are controlled by Update Rules, you will not be able to determine what is in
the Cube compared to what is in the R/3 environment. You will need to compare records on a 1:1 basis
against records in R/3 transactions for the functional area in question. I would recommend enlisting the
help of the end user community to assist since they presumably know the data.
To use RSA3, go to it and enter the extractor ex: 2LIS_02_HDR. Click execute and you will see the record
count, you can also go to display that data. You are not modifying anything so what you do in RSA3 has
no effect on data quality afterwards. However, it will not tell you how many records should be expected
in BW for a given load. You have that information in the monitor RSMO during and after data loads.
From RSMO for a given load you can determine how many records were passed through the transfer
rules from R/3, how many targets were updated, and how many records passed through the Update
Rules. It also gives you error messages from the PSA.
Q) Types of Transfer Rules?
A) Field to Field mapping, Constant, Variable & routine.
Q) Types of Update Rules?
A) (Check box), Return table
Q) Transfer Routine?
A) Routines, which we write in, transfer rules.
Q) Update Routine?
A) Routines, which we write in Update rules
Q) What is the difference between writing a routine in transfer rules and writing a routine in update
rules?
A) If you are using the same InfoSource to update data in more than one data target its better u write in
transfer rules because u can assign one InfoSource to more than one data target & and what ever logic
u write in update rules it is specific to particular one data target.
Q) Routine with Return Table.
A) Update rules generally only have one return value. However, you can create a routine in the tab strip
key figure calculation, by choosing checkbox Return table. The corresponding key figure routine then no
longer has a return value, but a return table. You can then generate as many key figure values, as you
like from one data record.
Q) Start routines?
A) Start routines u can write in both updates rules and transfer rules, suppose you want to restrict
(delete) some records based on conditions before getting loaded into data targets, then you can specify
this in update rules-start routine.
Ex: - Delete Data_Package ani ante it will delete a record based on the condition
Q) X & Y Tables?
X-table = A table to link material SIDs with SIDs for time-independent navigation attributes.
Y-table = A table to link material SIDs with SIDS for time-dependent navigation attributes.
There are four types of sid tables
X time independent navigational attributes sid tables
Y time dependent navigational attributes sid tables
H hierarchy sid tables
I hierarchy structure sid tables
Q) Filters & Restricted Key figures (real time example)
Restricted KF's u can have for an SD cube: billed quantity, billing value, no: of billing documents as
RKF's.
Q) Line-Item Dimension (give me an real time example)
Line-Item Dimension: Invoice no: or Doc no: is a real time example
Q) What does the number in the 'Total' column in Transaction RSA7 mean?
A) The 'Total' column displays the number of LUWs that were written in the delta queue and that have
not yet been confirmed. The number includes the LUWs of the last delta request (for repetition of a
delta request) and the LUWs for the next delta request. A LUW only disappears from the RSA7 display
when it has been transferred to the BW System and a new delta request has been received from
the BW System.
Q) How to know in which table (SAP BW) contains Technical Name / Description and creation data of a
particular Reports. Reports that are created using BEx Analyzer.
A) There is no such table in BW if you want to know such details while you are opening a particular
query press properties button you will come to know all the details that you wanted.
You will find your information about technical names and description about queries in the following
tables. Directory of all reports (Table RSRREPDIR) and Directory of the reporting component elements
(Table RSZELTDIR) for workbooks and the connections to queries check Where- used list for reports in
workbooks (Table RSRWORKBOOK) Titles of Excel Workbooks in InfoCatalog (Table RSRWBINDEXT)
Q) What is a LUW in the delta queue?
A) A LUW from the point of view of the delta queue can be an individual document, a group of
documents from a collective run or a whole data packet of an application extractor.
Q) Why does the number in the 'Total' column in the overview screen of Transaction RSA7 differ from
the number of data records that is displayed when you call the detail view?
A) The number on the overview screen corresponds to the total of LUWs (see also first question) that
were written to the qRFC queue and that have not yet been confirmed. The detail screen displays the
records contained in the LUWs. Both, the records belonging to the previous delta request and the
records that do not meet the selection conditions of the preceding delta init requests are filtered out.
Thus, only the records that are ready for the next delta request are displayed on the detail screen. In
the detail screen of Transaction RSA7, a possibly existing customer exit is not taken into account.
Q) Why does Transaction RSA7 still display LUWs on the overview screen after successful delta loading?
A) Only when a new delta has been requested does the source system learn that the previous delta was
successfully loaded to the BW System. Then, the LUWs of the previous delta may be confirmed (and
also deleted). In the meantime, the LUWs must be kept for a possible delta request repetition. In
particular, the number on the overview screen does not change when the first delta was loaded to the
BW System.
Q) Why are selections not taken into account when the delta queue is filled?
A) Filtering according to selections takes place when the system reads from the delta queue. This is
necessary for reasons of performance.
Q) Why is there a DataSource with '0' records in RSA7 if delta exists and has also been loaded
successfully?
It is most likely that this is a DataSource that does not send delta data to the BW System via the delta
queue but directly via the extractor (delta for master data using ALE change pointers). Such a
DataSource should not be displayed in RSA7. This error is corrected with BW 2.0B Support Package 11.
Q) Do the entries in table ROIDOCPRMS have an impact on the performance of the loading procedure
from the delta queue?
A) The impact is limited. If performance problems are related to the loading process from the delta
queue, then refer to the application-specific notes (for example in the CO-PA area, in the logistics
cockpit area and so on).
Caution: As of Plug In 2000.2 patch 3 the entries in table ROIDOCPRMS are as effective for the delta
queue as for a full update. Please note, however, that LUWs are not split during data loading for
consistency reasons. This means that when very large LUWs are written to the DeltaQueue, the actual
package size may differ considerably from the MAXSIZE and MAXLINES parameters.
Q) Why does it take so long to display the data in the delta queue (for example approximately 2 hours)?
A) With Plug In 2001.1 the display was changed: the user has the option of defining the amount of data
to be displayed, to restrict it, to selectively choose the number of a data record, to make a distinction
between the 'actual' delta data and the data intended for repetition and so on.
Q) What is the purpose of function 'Delete data and meta data in a queue' in RSA7? What exactly is
deleted?
A) You should act with extreme caution when you use the deletion function in the delta queue. It is
comparable to deleting an InitDelta in the BW System and should preferably be executed there. You do
not only delete all data of this DataSource for the affected BW System, but also lose the entire
information concerning the delta initialization. Then you can only request new deltas after another
delta initialization.
When you delete the data, the LUWs kept in the qRFC queue for the corresponding target system are
confirmed. Physical deletion only takes place in the qRFC outbound queue if there are no more
references to the LUWs.
The deletion function is for example intended for a case where the BW System, from which the delta
initialization was originally executed, no longer exists or can no longer be accessed.
Q) Why does it take so long to delete from the delta queue (for example half a day)?
A) Import PlugIn 2000.2 patch 3. With this patch the performance during deletion is considerably
improved.
Q) Why is the delta queue not updated when you start the V3 update in the logistics cockpit area?
A) It is most likely that a delta initialization had not yet run or that the delta initialization was not
successful. A successful delta initialization (the corresponding request must have QM status 'green' in
the BW System) is a prerequisite for the application data being written in the delta queue.
Q) What is the relationship between RSA7 and the qRFC monitor (Transaction SMQ1)?
A) The qRFC monitor basically displays the same data as RSA7. The internal queue name must be used
for selection on the initial screen of the qRFC monitor. This is made up of the prefix 'BW, the client and
the short name of the DataSource. For DataSources whose name are 19 characters long or shorter, the
short name corresponds to the name of the DataSource. For DataSources whose name is longer than
19 characters (for delta-capable DataSources only possible as of PlugIn 2001.1) the short name is
assigned in table ROOSSHORTN.
In the qRFC monitor you cannot distinguish between repeatable and new LUWs. Moreover, the data of
a LUW is displayed in an unstructured manner there.
Q) Why are the data in the delta queue although the V3 update was not started?
A) Data was posted in background. Then, the records are updated directly in the delta queue (RSA7).
This happens in particular during automatic goods receipt posting (MRRS). There is no duplicate transfer
of records to the BW system. See Note 417189.
Q) Why does button 'Repeatable' on the RSA7 data details screen not only show data loaded into BW
during the last delta but also data that were newly added, i.e. 'pure' delta records?
A) Was programmed in a way that the request in repeat mode fetches both actually repeatable (old)
data and new data from the source system.
Q) I loaded several delta inits with various selections. For which one is the delta loaded?
A) For delta, all selections made via delta inits are summed up. This means, a delta for the 'total' of all
delta initializations is loaded.
Q) How many selections for delta inits are possible in the system?
A) With simple selections (intervals without complicated join conditions or single values), you can make
up to about 100 delta inits. It should not be more.
With complicated selection conditions, it should be only up to 10-20 delta inits.
Reason: With many selection conditions that are joined in a complicated way, too many 'where' lines
are generated in the generated ABAP source code that may exceed the memory limit.
Q) I intend to copy the source system, i.e. make a client copy. What will happen with may delta? Should
I initialize again after that?
A) Before you copy a source client or source system, make sure that your deltas have been fetched from
the DeltaQueue into BW and that no delta is pending. After the client copy, an inconsistency might
occur between BW delta tables and the OLTP delta tables as described in Note 405943. After the client
copy, Table ROOSPRMSC will probably be empty in the OLTP since this table is client-independent.
After the system copy, the table will contain the entries with the old logical system name that are no
longer useful for further delta loading from the new logical system. The delta must be initialized in any
case since delta depends on both the BW system and the source system. Even if no
dump 'MESSAGE_TYPE_X' occurs in BW when editing or creating an InfoPackage, you should expect
that the delta have to be initialized after the copy.
Q) Is it allowed in Transaction SMQ1 to use the functions for manual control of processes?
A) Use SMQ1 as an instrument for diagnosis and control only. Make changes to BW queues only after
informing the BW Support or only if this is explicitly requested in a note for component 'BC-BW' or 'BWWHM-SAPI'.
Q) Despite of the delta request being started after completion of the collective run (V3 update), it does
not contain all documents. Only another delta request loads the missing documents into BW. What is
the cause for this "splitting"?
A) The collective run submits the open V2 documents for processing to the task handler, which
processes them in one or several parallel update processes in an asynchronous way. For this reason,
plan a sufficiently large "safety time window" between the end of the collective run in the source
system and the start of the delta request in BW. An alternative solution where this problem does
not occur is described in Note 505700.
Q) Despite my deleting the delta init, LUWs are still written into the DeltaQueue?
A) In general, delta initializations and deletions of delta inits should always be carried out at a time
when no posting takes place. Otherwise, buffer problems may occur: If a user started the internal mode
at a time when the delta initialization was still active, he/she posts data into the queue even
though the initialization had been deleted in the meantime. This is the case in your system.
Q) In SMQ1 (qRFC Monitor) I have status 'NOSEND'. In the table TRFCQOUT, some entries have the
status 'READY', others 'RECORDED'. ARFCSSTATE is 'READ'. What do these statuses mean? Which values
in the field 'Status' mean what and which values are correct and which are alarming? Are the statuses
BW-specific or generally valid in qRFC?
A) Table TRFCQOUT and ARFCSSTATE: Status READ means that the record was read once either in a
delta request or in a repetition of the delta request. However, this does not mean that the record has
successfully reached the BW yet. The status READY in the TRFCQOUT and RECORDED in the ARFCSSTATE
means that the record has been written into the DeltaQueue and will be loaded into the BW with the
next delta request or a repetition of a delta. In any case only the statuses READ, READY and RECORDED
in both tables are considered to be valid. The status EXECUTED in TRFCQOUT can occur temporarily. It is
set before starting a DeltaExtraction for all records with status READ present at that time. The records
with status EXECUTED are usually deleted from the queue in packages within a delta request directly
after setting the status before extracting a new delta. If you see such records, it means that either a
process which is confirming and deleting records which have been loaded into the BW is successfully
running at the moment, or, if the records remain in the table for a longer period of time with status
EXECUTED, it is likely that there are problems with deleting the records which have already been
successfully been loaded into the BW. In this state, no more deltas are loaded into the BW. Every other
status is an indicator for an error or an inconsistency. NOSEND in SMQ1 means nothing (see note
378903).
The value 'U' in field 'NOSEND' of table TRFCQOUT is discomforting.
Q) The extract structure was changed when the DeltaQueue was empty. Afterwards new delta records
were written to the DeltaQueue. When loading the delta into the PSA, it shows that some fields were
moved. The same result occurs when the contents of the DeltaQueue are listed via the detail display.
Why are the data displayed differently? What can be done?
Make sure that the change of the extract structure is also reflected in the database and that all servers
are synchronized. We recommend to reset the buffers using Transaction $SYNC. If the extract structure
change is not communicated synchronously to the server where delta records are being created, the
records are written with the old structure until the new structure has been generated. This may have
disastrous consequences for the delta.
When the problem occurs, the delta needs to be re-initialized.
Q) How and where can I control whether a repeat delta is requested?
A) Via the status of the last delta in the BW Request Monitor. If the request is RED, the next load will be
of type 'Repeat'. If you need to repeat the last load for certain reasons, set the request in the monitor
to red manually. For the contents of the repeat see Question 14. Delta requests set to red despite
of data being already updated lead to duplicate records in a subsequent repeat, if they have not been
deleted from the data targets concerned before.
Q) As of PI 2003.1, the Logistic Cockpit offers various types of update methods. Which update method is
recommended in logistics? According to which criteria should the decision be made? How can I choose
an update method in logistics?
See the recommendation in Note 505700.
Q) Are there particular recommendations regarding the data volume the DeltaQueue may grow to
without facing the danger of a read failure due to memory problems?
A) There is no strict limit (except for the restricted number range of the 24-digit QCOUNT counter in the
LUW management table - which is of no practical importance, however - or the restrictions regarding
the volume and number of records in a database table).
When estimating "smooth" limits, both the number of LUWs is important and the average data volume
per LUW. As a rule, we recommend to bundle data (usually documents) already when writing to the
DeltaQueue to keep number of LUWs small (partly this can be set in the applications, e.g. in the
Logistics Cockpit). The data volume of a single LUW should not be considerably larger than 10% of
the memory available to the work process for data extraction (in a 32-bit architecture with a memory
volume of about 1GByte per work process, 100 Mbytes per LUW should not be exceeded). That limit is
of rather small practical importance as well since a comparable limit already applies when writing to
the DeltaQueue. If the limit is observed, correct reading is guaranteed in most cases.
If the number of LUWs cannot be reduced by bundling application transactions, you should at least
make sure that the data are fetched from all connected BWs as quickly as possible. But for other, BWspecific, reasons, the frequency should not be higher than one DeltaRequest per hour.
To avoid memory problems, a program-internal limit ensures that never more than 1 million LUWs are
read and fetched from the database per DeltaRequest. If this limit is reached within a request, the
DeltaQueue must be emptied by several successive DeltaRequests. We recommend, however, to try not
to reach that limit but trigger the fetching of data from the connected BWs already when the
number of LUWs reaches a 5-digit value.

o LBWF Log for LO Extract Structures
o RSA7 BW Delta Queue Monitor
3. How to create a connection with LIS InfoStructures?
LBW0 Connecting LIS InfoStructures to BW
4. What is the difference between ODS and InfoCube and MultiProvider?
ODS: Provides granular data, allows overwrite and data is in transparent tables, ideal for drilldown and
RRI.
CUBE: Follows the star schema, we can only append data, ideal for primary reporting.
MultiProvider: Does not have physical data. It allows to access data from different InfoProviders (Cube,
ODS, InfoObject). It is also preferred for reporting.
5. What are Start routines, Transfer routines and Update routines?
Start Routines: The start routine is run for each DataPackage after the data has been written to the PSA
and before the transfer rules have been executed. It allows complex computations for a key figure or a
characteristic. It has no return value. Its purpose is to execute preliminary calculations and to
store them in global DataStructures. This structure or table can be accessed in the other routines. The
entire DataPackage in the transfer structure format is used as a parameter for the routine.
Transfer / Update Routines: They are defined at the InfoObject level. It is like the Start Routine. It is
independent of the DataSource. We can use this to define Global Data and Global Checks.
6. What is the difference between start routine and update routine, when, how and why are they
called?
Start routine can be used to access InfoPackage while update routines are used while updating the Data
Targets.
7. What is the table that is used in start routines?
Always the table structure will be the structure of an ODS or InfoCube. For example if it is an ODS then
active table structure will be the table.
8. Explain how you used Start routines in your project?
Start routines are used for mass processing of records. In start routine all the records of DataPackage is
available for processing. So we can process all these records together in start routine. In one of
scenario, we wanted to apply size % to the forecast data. For example if material M1 is forecasted to
say 100 in May. Then after applying size %(Small 20%, Medium 40%, Large 20%, Extra Large 20%), we
wanted to have 4 records against one single record that is coming in the info package. This is achieved
in start routine.
9. What are Return Tables?
When we want to return multiple records, instead of single value, we use the return table in the Update
Routine. Example: If we have total telephone expense for a Cost Center, using a return table we can get
expense per employee.
10. How do start routine and return table synchronize with each other?
Return table is used to return the Value following the execution of start routine
11. What is the difference between V1, V2 and V3 updates?
V1 Update: It is a Synchronous update. Here the Statistics update is carried out at the same time as the
document update (in the application tables).
V2 Update: It is an Asynchronous update. Statistics update and the Document update take place as
different tasks.
V1 & V2 don't need scheduling.
Serialized V3 Update: The V3 collective update must be scheduled as a job (via LBWE). Here, document
data is collected in the order it was created and transferred into the BW as a batch job. The transfer
sequence may not be the same as the order in which the data was created in all scenarios. V3 update
only processes the update data that is successfully processed with the V2 update.
12. What is compression?
It is a process used to delete the Request IDs and this saves space.
13. What is Rollup?
This is used to load new DataPackages (requests) into the InfoCube aggregates. If we have not
performed a rollup then the new InfoCube data will not be available while reporting on the aggregate.
14. What is table partitioning and what are the benefits of partitioning in an InfoCube?
It is the method of dividing a table which would enable a quick reference. SAP uses fact file partitioning
to improve performance. We can partition only at 0CALMONTH or 0FISCPER. Table partitioning helps to
run the report faster as data is stored in the relevant partitions. Also table maintenance becomes
easier. Oracle, Informix, IBM DB2/390 supports table partitioning while SAP DB, Microsoft SQL Server,
IBM DB2/400 do not support table portioning.
15. How many extra partitions are created and why?
Two partitions are created for date before the begin date and after the end date.
16. What are the options available in transfer rule?
¢ InfoObject
¢ Constant
¢ Routine
¢ Formula
17. How would you optimize the dimensions?
We should define as many dimensions as possible and we have to take care that no single dimension
crosses more than 20% of the fact table size.
18. What are Conversion Routines for units and currencies in the update rule?
Using this option we can write ABAP code for Units / Currencies conversion. If we enable this flag then
unit of Key Figure appears in the ABAP code as an additional parameter. For example, we can convert
units in Pounds to Kilos.
19. Can an InfoObject be an InfoProvider, how and why?
Yes, when we want to report on Characteristics or Master Data. We have to right click on the InfoArea
and select "Insert characteristic as data target". For example, we can make 0CUSTOMER as an
InfoProvider and report on it.
20. What is Open Hub Service?
The Open Hub Service enables us to distribute data from an SAP BW system into external Data Marts,
analytical applications, and other applications. We can ensure controlled distribution using several
systems. The central object for exporting data is the InfoSpoke. We can define the source and the target
object for the data. BW becomes a hub of an enterprise

Q) Statistical Update?
A) ?
Q) What are Process Chains?
A) TCode is RSPC, is a sequence of processes scheduled in the background & waiting to be triggered by a
specific event. Process chains nothing but grouping processes. Process variant (start variant) is the place
the process chain knows where to start.
There should be min and max one start variant in each process chain, here we specify when should the
process chain start by giving date and time or if you want to start immediately
Some of theses processes trigger an event of their own that in-turn triggers other processes.
Ex: - Start chain â ' Delete BCube indexes â ' Load data from the source system to PSA â '
Load data from PSA to DataTarget ODS â ' Load data from ODS to BCube â ' Create Indexes for BCube
after loading data â ' Create database statistics â ' Roll-Up data into the aggregate â ' Restart chain
from beginning.
Q) What are Process Types & Process variant?
A) Process types are General services, Load Process & subsequent processing, Data Target
Administration, Reporting agent & Other BW services.
Process variant (start variant) is the place the process type knows when & where to start.
Q) Difference between MasterData & Transaction InfoPackage?
A) 5 tabs in Masterdata & 6 tabs in Transaction data, the extra tab in Transaction data is DATA TARGETS.
Q) Types of Updates?
A) Full Update, Init Delta Update & Delta Update.
Q) For Full update possible while loading data from R/3?
A) InfoPackage â ' Scheduler â ' Repair Request flag (check).
This is only possible when we use MM & SD modules.
Q) Why it takes more time while loading the transaction data even to load the transaction without
master data (we check the checkbox, Always Update data, even if no master data exits for the data)?
A) Because while loading the data it has to create SID keys for transaction data
