A higher access user just enabled the ADVANCED BILL OF MATERIALS feature 3 months ago.. and now as i check every Work Order needs to have "Bill of Materials" and "Bill of Materials Revision" in order to be Build.. Every time I edit the Work Order and fill-up the default bill of material and bill of material revision of an assembly the items that was inputted by the user before are gone and the default items indicated on the "Bill of Materials Revision" are now populated...Is there a way to restrict changing the items after selecting the Bill of Materials?? It takes us a lot of time in input again the right materials of the certain Work Order
