Assigning Material Components 
Assigning Material Components
Use
If you would like to plan the use of material components, you have to assign the BOM items of the production lot to the routing of the production lot.
Prerequisites
You have created a routing for the production lot or assigned the material of the production lot to an existing routing.
Features
If you use a WBS BOM for the production lot, the system offers you the items from this BOM for the assignment. The same applies if you use a material BOM for the production lot.
Initially without reference to the production lot, you can assign the material BOM items to operations of a routing. If you then assign the material BOM and routing to a production lot, the component assignment remains; that is, you do not have to re-assign the items. If necessary, you can change the component assignment.
