The system calculates Component Availability status only for the base process order in the joint order set. The Component Availability status for all co- and by-product orders is always No Status.

This is because the base process order in the joint set contains all components and routings of the joint product. Co-/by-product orders do not have components or routings; therefore, they have no Component Availability status to calculate. Also, the base process order is always shown in the MSW and PSW, while co-/by-product orders are only visible in the MSW. So, the system calculates the base process order component availability.
