During production order creation, several valid production versions are found.

The system chooses the production version based on the validity period and the sales order. The validity period determines whether the production version is valid for the planned start date of the production order. The sales order determines whether the production version is assigned to a specific sales order item or not. If there are multiple production versions that meet these criteria, the system chooses the one with the lowest alphanumeric value. References: [SAP S/4HANA Production Planning and Manufacturing Certification Guide], page 113; [SAP Help Portal: Production Version]
