General
•
•
CBP is a branch of MRP dealing with all those materials whose
planning is a function of their consumption, as opposed to how
much is currently needed for production or to fulfill customer
demand
In accordance with the above, we will use CBP for less expensive,
less critical components. That is, those less expensive
components that we usually purchase from external vendors (e.g.,
nuts and bolts).

Categorization
•
•
•
•
Categorization of products is about defining the delivery time and
the delivery service for each of the products in the product
program. Categorization of the products is made from a
categorization of the customers and the products they buy.
Subsequently the categories for the finished products are then
linked to the semi-finished and the raw materials respectively, and
later also to suppliers
With categories at each level it is possible to create a very
efficient supply chain
Product Categorization gives a superb basis for implementing
Lean Manufacturing, by clearly showing the product priority when
it comes to flow, inventory, planning, etc.

ABC Approach
•
•
One of the common practices for categorizing materials is the
ABC approach
In principal, the ABC approach says: Categorize your materials
according to the following simple rule:
 A – “A” materials are the most expensive and critical materials
in your organization
 B – “B” materials are the less expensive, less critical materials
in your organization
 C – “C” materials are the non-expensive, non-critical materials
in your organization
10
When to Use CBP
•
•
•
CBP deals primarily with the “C” materials that we purchase
One of the purposes of CBP is to create Purchase Orders as
automatically as possible in order to reduce manual intervention
in the purchase process
It is possible to use transaction MIBC (ABC Analysis for Cycle
Counting) as a basis for ABC categorization. However, it does not
take into account the criticality of the material, and therefore
manual work must still be performed.

General
•
•
Reorder point planning should be used with relatively constant
consumption materials
If the material’s consumption is not constant over time, this
method might result in excess stock (the need to keep high safety
stock) or stock shortage (fluctuations)
13
Methodology
Reorder point quantity
includes safety stock. The PO
quantity depends on the lot
size (e.g., fixed).
14
Calculation
MRP
compares the
quantity in
stock + PRs
+ POs to the
reorder point.
There is a
shortage if
the total
quantity is
lower than
the reorder
point.

Forward Scheduling
CBP calculates the availability date depending on lead
times from today’s date

Planning Based on Past Consumption
•
•
•
Planning based on past consumption should be used for
materials whose future behavior can be predicted by their past
consumption
Materials with short life cycle would therefore probably not be a
good choice for planning using this method
Good candidates for planning using this method might be
materials with relatively many consumption periods

General
•
•
•
Time-phased planning should be used for materials that are
delivered on specific dates
This method works similarly to reorder point planning — the
difference is that specific delivery dates are taken as parameter
To run this method, a specific calendar must be created and
maintained
21
How Time-Phased Planning Works
22
Methodology
Time-phased planning works almost the same way as reorder
point planning, only with specific GR dates

7 Key Points to Take Home
•

•
•
Categorize your materials
Use CBP for your “C” components
Materials with relatively constant consumption should be planned
with reorder point planning
Materials with numerous consumption histories may make use of
forecasting to predict their future consumption
Materials with specified delivery dates may use time-phased
planning
Forecasting may be used also to calculate safety stock and
reorder points according to past consumption figures
Creating a new MRP type can be useful to control customized
planning methodology as combination of “standard” methods
