In SAP S/4HANA,lead time schedulingfor a production order (e.g., in CO01, Scheduling Type: Lead Time Scheduling) calculates detailed operation dates using routing data and buffers. Relevant time elements include:

Float after production(C): Defined in the material master (MRP 2 view, field: Float After Production) or scheduling margin key (Customizing, OPPT), this buffer time after the last operation ensures flexibility before the order’s end date (e.g., for quality checks), extending the total lead time.

Setup time(D): Maintained in the routing (CA01, Standard Values, field: Setup Time), this is the time to prepare the work center for an operation. It’s included in the operation duration (calculated via work center formulas, CR02), directly impacting the lead time schedule.

Opening period(A) (MRP 2 view) is a buffer before production starts, relevant for order release, not lead time scheduling within the order.Total replenishment lead time(B) (MRP 2 view) is a high-level estimate for MRP, not detailed operation scheduling. This is per SAP’s lead time scheduling rules.

Thelow-level codein SAP S/4HANA (visible in MD04 or calculated during MRP) indicates the deepest level at which a material appears in any BOM across all products, starting from 000 (finished goods) downward. Its key features are:

To determine how costs are rolled up by product costing(B): In Product Costing (CO-PC), the low-level code ensures costs are calculated bottom-up, starting with the lowest-level components (e.g., raw materials) and rolling up through assemblies to the finished product (transaction CK11N). This guarantees accurate cost aggregation.

To determine the sequence in which materials are planned in MRP(C): During MRP (MD01/MD02), the system plans materials in ascending order of low-level codes (lowest first), ensuring dependent requirements for lower-level components are calculated before higher-level assemblies, avoiding planning gaps.

Priority of alternative components in ATP(A) is managed by BOM alternative item strategies (e.g., 100% check), not low-level codes.Use of sub-items in BOM(D) is defined by item categories (e.g., "R"), not influenced by low-level codes. This is per SAP’s planning and costing logic.

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.
