Object documentation Requirements Strategy 

Definition

Determines how production quantities are planned in SAP APO and how the forecast is consumed by other orders.

Use

This graphic is explained in the accompanying text

 

Basically, the requirements strategy assigns an (ATP) category for the forecast (such as FA or FC) to an (ATP) category group that can consume the forecast. The category group can consist of one or more categories. Therefore, in the above example, forecast order category FA can be consumed by the following:

·  Reservations (AM)

·  Dependent demand (AY)

·  Sales orders (BM)

·  Customer requirements (BS)

Planned Independent Requirements (PIR) Segment

In SAP APO, the quantities for make-to-order operations are, in general, planned separately to those for make-to-stock operations. These areas are known as PIR segments.

In general, you can only plan within a PIR segment. This means that you cannot consume planned independent requirements for a make-to-stock scenario with sales orders in a make-to-order scenario.

However, SAP does offer a special segment to cover exactly this situation – PIR segment Planning without final assembly, without individual requirements. For more information, see the input help for the PIR Segment field in the requirements strategy.

Note

Supply Network Planning (SNP) cannot work with the individual customer segment. For example, demand in this segment is not shown in SNP. Consequently, you should not use requirements strategies that use this segment. In the standard system, these are the strategies 30 and 40.

 

Assignment Mode

The assignment mode determines how sales orders consume the forecast, and whether final assembly is taken into account. It corresponds to the allocation indicator in SAP R/3. This indicator is assigned to the sales order via the requirements class. Both fields must have the same value for consumption to take place. To gain an overview of this function in SAP R/3, see the SAP Library for SAP R/3 in the Demand Management (PP-MP-DEM) component under Determination of the Requirements Type.

Note

The requirements strategy is equivalent to the planning strategy in SAP R/3. However, the functionality is simpler than that in SAP R/3.

 

SAP provides four strategies in the standard system:

10  Anonymous make-to-stock production

20  Planning with final assembly

30  Planning without final assembly

40  Planning product

If these are not sufficient for your needs, you can create your own requirements strategies in Customizing for SAP APO under Master Data ® Specify Requirements Strategies.

 

You specify a requirements strategy for a product in the location product master record on the Demand tab page. If the forecast is to be consumed, you must specify a requirements strategy.

You can specify the consumption mode and the length of the relevant consumption period in the Consumption section of the same screen. However, if you do not, the system consumes any independent requirements that lie within the same planning bucket as the sales order.
