Subcontracting in MRP
TOP Item: General Information See the following central SAP Note related to the Simplification Item: 2268044
TOP Item Information General Presentation
Simplification List Item Description SAP ERP had three different ways of planning parts to be provided to a subcontractor: • Planning subcontracting demand together with internal demand in the make-to-stock planning segment (3.0 logic) • Separating subcontracting demand and stock into single subcontracting planning segments and planning uncovered subcontracting demand together with internal demand in the make-to-stock planning segment (4.0 logic) • Planning the demand of each subcontractor separately using subcontracting MRP areas (available from SAP ERP release 4.5) In SAP S/4HANA 1511, the 4.0 logic was removed while the 4.5 logic was simplified. The SAP S/4HANA MRP uses default planning parameters if MRP area –specific material master records do not exist. You only have to create an MRP area for every subcontractor. Of course, it is still possible to create MRP area/supplier-specific material master data if required.
Business Impact
Specific
The default way of planning parts to be provided to subcontractors is based on MRP areas. A subcontracting MRP area should be created for every subcontractor. You do not have to create an MRP area-specific material master record for every part to be provided to the subcontractor but of course this is possible if you want to overrule the default planning parameters.
Required and Recommended Action(s) If you have several subcontractors requiring the same component materials and if you do not yet use MRP areas to plan the required components then proceed as follows: • Create MRP areas for e very subcontractor (can be done before or after upgrade) • Run regenerative MRP after the upgrade

ERP
The customizing entry for the supplier is sufficient to trigger stock transfer reservations from plant to the SC MRP area for all components to be provided to this supplier Material assignments are only required for special functional needs regarding the provision process (usage of purchase requisitions/orders, SC 3rd party order processing, lot sizing, etc.)
