Lock Cost Element into a WBE element
I want to lock all movements (CO-FI-MM) for a WBE with a Cost Element. How to do this? It's possible with a GGB0 validation?
I'm thinking about put the Cost Element code in a WBE master data field (I don't know which one yet). Then create a validation that check in Co tables that all costs movements (not budgeting) for a WBE element has the correct cost element.
How to do this?
Thanks a lot. Regards
