Which of the following elements does MRP take into account during net requirement calculation?

Material Requirements Planning (MRP) in SAP S/4HANA calculates net requirements to determine material shortages or surpluses by comparing the available stock and scheduled receipts against requirements. During this calculation, MRP considers existingproduction orders(A) because they represent firm commitments to produce materials, and their quantities directly influence the availability of components and finished goods. Similarly,planned orders (firmed)(B) are included as they are confirmed planning proposals that have been manually or automatically fixed, ensuring they are treated as reliable supply elements in the net requirement calculation.

Planned orders (unfirmed)(C) are not considered firm receipts because they are still tentative and subject to change during subsequent MRP runs, so they are excluded from the net calculation unless firmed.ATP (Available-to-Promise) quantities(D) are used in availability checks for sales orders, not directly in MRP’s net requirement calculation, which focuses on stock and scheduled receipts rather than promise-based quantities. This aligns with SAP’s MRP logic as outlined in the SAP S/4HANA Production Planning documentation, emphasizing firm supply elements.
