Aggregation of Demands Within the BOD
There is no source determination within a bill of distribution (BOD). Distribution requirements planning (DRP) aggregates the net demands of each child location to the next parent location so that all demands along the BOD arrive at the entry location. The net demands of the child locations are thus dependent demands of the parent location. DRP calculates the date at which you can cover the demands of the child locations by backwards scheduling and the relevant procurement lead time. For more information, see Calculation of Lead Times in DRP.
If contract packagers (CPs) exist for location products, DRP aggregates the demands depending on the deployment indicators along the BOD via the CPs.
Distribution requirements planning creates a consolidated view at the entry location of the BOD by rolling up not only demands but also excess stock along the distribution network. To make the system create the consolidated view, on the SAP Easy Access
screen,
choose . In the product master data, on the Properties of SPP
tab
page, in the Settings
screen area, select the Glb. Stk Entry Loc.
(DRP: Global Stock on Entry Location) checkbox.
To calculate global stock at the entry location of the BOD, you must activate the SCM-APO-SPP, Service Parts Planning 1
(SCM_APO_SPP_GEN_1
) business function. For more information, see SCM-APO-SPP,
Service Parts Planning 1.
If the net demand of a location product, whose location is not an entry location, is greater than zero in a period, DRP forwards this net demand to the parent location. In doing so DRP aggregates the net demands of all child locations at a parent location. It also creates a data record for each of these net demands. This data record contains the following information:
The ordered product
The parent location of the location that reports a demand
The location that reports a demand
Time stamp that specifies when the goods must be sent by
This time stamp results from the time stamp that specifies when the goods are needed and a backwards scheduling by the procurement lead time. If this time stamp specifies an earlier date, the system aggregates the demand to the overdue demands at the parent location.
