A production version is a master data object that links a bill of material (BOM) and a routing or a production process model (PPM) for a material. A production version is required for creating a production order in SAP S/4HANA, as it determines the components, operations, and resources that are needed for producing the material. You can create a production version manually or automatically using the CS_BOM_PRODVER_MIGRATION02 report1.

If you are trying to create a production order and no valid production version can be selected, it could be because of the following reasons:

No bills of material (BOMs) are assigned to the production versions (A): A BOM is a master data object that defines the components and the quantities that are required for producing a material. A production version must have a valid BOM assigned to it, otherwise it cannot be used for creating a production order. You can assign a BOM to a production version on the MRP 4 tab page of the material master2.

The order lot size is not within the validity range of a production version ©: A production version has a validity range that defines the period and the lot size interval in which it can be used for production planning. The validity range is maintained on the MRP 4 tab page of the material master2. If the order lot size (the quantity of the material to be produced) is not within the lot size interval of any production version, then no valid production version can be selected for creating a production order.

The other options are not valid reasons for not being able to select a production version for creating a production order:

All production versions for the material are locked (B): A production version can have a status that indicates whether it is active or locked. A locked production version cannot be used for production planning, but it can still be selected for creating a production order. However, the system will issue a warning message that the production version is locked and ask for confirmation before proceeding with the order creation3.

No production lines are assigned to the production versions (D): A production line is an organizational unit that represents a group of resources that are used for producing a material. A production line can be assigned to a production version on the MRP 4 tab page of the material master2. However, this assignment is optional and not mandatory for creating a production order. A production line can be used for grouping production versions for reporting or analysis purposes, but it does not affect the selection of a production version for creating a production order4.
