In classic MRP within SAP S/4HANA, scheduling agreements can be leveraged to automatically generate schedule lines for external procurement when a material shortage occurs. To enable this, the scheduling agreement must be maintained in thesource listand marked asMRP-relevant(B). This is done in transaction ME01 (Maintain Source List), where the scheduling agreement number is entered, and the "MRP" indicator (field: Source List Usage in MRP) is set to "1" (Relevant for MRP). This ensures MRP recognizes the agreement as a valid supply source.
Additionally, on the initial screen of the MRP run (e.g., transaction MD01 or MD02), you mustset the creation indicator for delivery schedule lines(C) to "1" (Create Schedule Lines). This parameter (field: Create Purchase Reqs) instructs MRP to generate schedule lines directly against the scheduling agreement instead of purchase requisitions. Option A (purchase requisitions) would create requisitions instead of schedule lines, which is not the goal. Option D (quota arrangement) is an alternative sourcing method but not required for scheduling agreements in this scenario.
