Session 4: The HANA Curriculum and Demos Dr. Bjarne Berg Associate professor Computer Science Lenoir-Rhyne University Introduction This last session is more technical as we explore what ETL options HANA has, what applications exists and review some core exercises students in the SAP University Alliance completes as part of their curriculum. We also see demos of BO Explorer on SAP HANA and a demo of the new BusinessObjects BI 4.1 tool suite and integrated BI environment on-top of HANA We end with an overview of where you can get more information about HANA and have a quick round with questions and answers. 2 Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers 3 HANA – The Detailed Architecture Modeling in SAP HANA HANA Applications Overview and Discussion Views in SAP HANA • Attribute views Represent master data (attributes, texts, hierarchies) Provide reusable dimensions for analytic and calculation views • Analytic views Join facts with relevant attribute dimensions • Calculation views Address more complex requirements than analytic views Can include both tables and views Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers 8 Exercise #1 Using SAP HANA and BO Explorer 1. In this first exercise, the students access SAP HANA through an Information Space Some of the Different BusinessObjects BI tools that can access HANA BO Explorer on SAP HANA BO Explorer on HANA Demo Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers 13 Data Provisioning Trigger Based Replication • SAP LT Replication Server Trigger-based concept that only considers the tables relevant for data replication Allows real-time (and scheduled) data replication from SAP ERP Systems and non-SAP systems (SAP supported databases only) into HANA Based on the SLO (System Landscape Optimization) technology SAP LT Replication Server Source System RFC connection SAP HANA DB connection ETL Based replication with DataServices DataServices – The work environment Data flows Vs. Workflows • Data flows • Extract, transform and load data (ETL process) Determines the flow of data – from the source to the target Similar to SAP BW transformations with data source and data target Workflows Optional objects Organize data flows Define the decision-making process to execute data flows and organizes data flows Similar to SAP BW process chains for automation of complex schedules Source Target Definitions and Metadata • • • Datastores: Provide the logical connection to a database (must be specified for each source and target database) Are used to import metadata for source and target databases Are used to read data from source tables and load data to target tables Metadata includes: Database tables: Table name, Column names, Column data types, Primary key columns, Table attributes RDBMS functions Application-specific data structures Connection metadata is defined in the object library as Datastores (for tables) and file formats (for flat files) Importing Metadata from HANA • • Import the metadata of the database tables (e.g. master data and transaction data tables), which should be populated at the end of the ETL process Examples: Customer attributes table (master data) Sales data table (transaction data) Table‘s metadata Import datastore tables Name CUSTOMER_N UMBER CUSTOMER_N AME CITY VALID_TO VALID_FROM SALES_ORGA NIZATION COUNTRY Key Data type Length (Dim) X VARCHAR 10 VARCHAR 20 VARCHAR DATE DATE VARCHAR 35 VARCHAR 2 X 4 Creating a Dataflow Query mapping and transformations • • The query transform enables you to select data from a source, filter or reformat the data and move it to the target You need to create a relationship between the input and output schemas for the data to move from the source to the target BW ETL Vs.

In this HANA case study, the students load data to SAP HANA Then they create attribute and analytical views Finally, they deploy it to BO Explorer Creating a new Datastores in BOBJ DataServices Importing table definition Result Linking to Flat file Defining flat file Result 35 Student’s do the same for Products and sales flat files Creating a Project and adding Dataflow Linking to flat file and make it a source Mapping flat file Source to Target table in HANA Executing the job and Monitoring Progress Result inside HANA viewed using HANA Studio Creating an Attribute View Adding table joins to more Customer Information Applying a Filter to an Attribute View Deciding what Users Should See and assign Key Attribute Validate and Activate a View Creating an Analytical View Data Foundations and Logical Joins Adding a Calculated Field to an Analytical View Multi-Currency Handling The Resulting Analytical View Deploying Analytical View in BO Explorer Building an Information Space The Result in BO Explorer Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers 50 BOBJ BI 4.1 (new release) on HANA Demo Session Agenda • Introduction • HANA Overview • SAP University Alliance: Student Exercise and Demo: BO Explorer on HANA • Overview of Extract, Transform and Load (ETL) into HANA • SAP University Alliance: Student Exercise – Step-by-Step • Demo: BI 4.1 (new) on HANA • Where to Find More Information • Questions and Answers 52 Good Sources for Getting up-to-speed – SAPHana.com Good Sources for Getting up-to-speed: experienceHana.com Good Sources for Getting up-to-speed: InsiderLeaningNetwork.com Good Sources for Getting up-to-speed: scn.sap.com/community/developer-center/hana Good Sources for Getting up-to-speed: SAP HANA Book on Amazon Good Sources for Getting up-to-speed: SAP University Alliances Questions and Answers Dr. Berg Bergb@lr.edu
