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.

SAP’sclean coreapproach for S/4HANA Cloud Private Edition aims for a standardized, upgrade-friendly system. Recommended guiding principles include:

Establish an organizational structure, technical foundation, and transformation methodology for clean core(A): SAP advises setting up a governance structure, technical standards (e.g., extensibility via SAP BTP), and a methodology (e.g., SAP Activate) to ensure clean core adoption, minimizing customizations from the start.

Establish release management(C): Effective release management (e.g., via SAP Solution Manager or SAP Cloud ALM) ensures regular updates are applied smoothly, maintaining a clean core by avoiding conflicts with custom code and leveraging new standard features.

Define roles and responsibilities as part of a process transformation office(E): A dedicated transformation office with clear roles (e.g., process owners, IT architects) oversees clean core adherence, ensuring accountability for standardization and extensibility across teams.

Integrate clean core practices in the end-to-end value process chain(B) is a goal, not a distinct principle—it’s an outcome of other principles.Regular housekeeping tasks(D) (e.g., data archiving) supports operations but isn’t a core clean core principle, which focuses on design and governance. This is per SAP’s clean core strategy.

In SAP S/4HANA, MRP usesbackward schedulingto calculate the basic dates for dependent requirements (e.g., components needed for production). Backward scheduling starts from the requirement date of the finished product and works backward to determine when components must be available. The key time elements considered are:

Planned delivery time(A): This is maintained in the material master (MRP 2 view, field: Planned Delivery Time) for externally procured materials. It represents the time required by the vendor to deliver the material, and MRP uses it to calculate the start date for procurement to ensure the component is available when needed.

In-house production time(D): For materials produced in-house, this is maintained in the material master (MRP 2 view, field: In-house Production Time). It defines the total time required to produce the material, independent of quantity, and MRP uses it to determine the start date of production for dependent requirements.

Total replenishment lead time(B) (MRP 2 view, field: Total Replenishment Lead Time) is an optional field that includes all procurement and production times but is typically used as a fallback or for special cases, not as a standard element in backward scheduling for components.Operation duration(C) is specific to routing data (e.g., setup, processing times) and is considered in detailed scheduling (e.g., production order scheduling), not MRP’s basic date calculation, which relies on material master data. This aligns with SAP’s MRP scheduling logic as per official documentation.
