We use a combination of PS and PP. At the lower level sub assembly we use production planning and at the upper level sub assembly and FG we use project systems.
For the lower level sub assembly we attach the material into the project builder (CJ20N), we maintain a production BOM and after running MRP (MD02) we have planned orders generated which are eventually converted into production order. Now this is where the problem lies: We need this production order to be settled to a network instead of a WBS. The production order account assignment has the WBS, there is no option to have the network as an account assignment.
Any help would be greatly appreciated and points rewarded.
