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.
