hi all , im looking help on the following problem , we currently use configurable materials to manufacture product , currently when an order BOM is created for a sales order using a standard material BOM and for example a part is removed from a phantom assembly and reaplced with a new special part , what happens next is that withi nthe routing the full material unallocates from the phantom group and defaults to unallocated even though in the master routing the parts that were not changed in the phantom are still allocated in the routing screen under an allocated opertion number , the production orders when released to make the product are all incorrect and causing problems and the materials are having to be manaully allocated in the production order
