Quantity Structure Control in Joint Production 
Use
The quantity structure to be costed is determined by data from the material master.
Features
To determine the quantity structure for costing co-products, enter one of the following parameters in the material master:
A production version with BOM and routing entries
A production version that refers to a leading co-product or a process material
Note
This link enables you to cost a co-product from the quantity structure of another leading co-product. This ensures that when you cost this co-product, costing is carried out using the BOM and routing of the leading co-product.
The costing lot size is dependent on the costing lot size of the leading co-product and the component quantity in the BOM.
( )
If no entries were made in the material master of the co-product, the system attempts to determine the quantity structure through the quantity structure determination of the costing variant. It first attempts to determine the quantity structure via valid production versions.
