Assign New Project Account Assignment to Material Components 
Use
In Sales Order Management, the sales order is assigned to a WBS element account. In the planning run, procurement proposals for all dependent materials that are included in the project structure are assigned to the WBS account to which the sales order is assigned.
If you want to assign certain assemblies and material components to the account of a sub-project of the project structure, you can use this function to assign the material numbers to the WBS elements of the sub-project.
In the planning run, the material component determined here and all materials dependent on this material are assigned to the sub-project account.
Prerequisites
You have assigned a WBS element to the sales order.
Procedure
The system displays the Process project allocation screen.
