For a production version to be valid and consistent, what requirements must be fulfilled?

A production version in SAP S/4HANA (material master, MRP 4 view) links a BOM and routing for production. For it to be valid and consistent:

The deletion flag must NOT be set for the bill of material (BOM) or the routing(A): If the BOM (CS02) or routing (CA02) has a deletion flag, it cannot be used in production planning or execution, rendering the production version invalid. This is a basic integrity check in SAP.

The assigned routing and bill of material (BOM) must be valid in the entire validity period(C): The production version’s validity period (e.g., Valid From/To dates) must align with the BOM and routing’s validity. If either expires or is invalid during the version’s timeframe, the system cannot use it (checked in MRP or order creation).

The lot size range must be within the lot size range of the assigned routing(E): The production version’s lot size (MRP 4 view) must fall within the routing’s lot size range (CA02, header data). If the order quantity exceeds this range, the version is inconsistent for planning.

The consistency check(B) (transaction C252) is a manual validation tool, not a requirement for validity—it’s optional.Same validity period(D) is not mandatory; overlapping validity is sufficient, as long as both are valid when needed. This is per SAP’s production version documentation.
