Customer hope there will some setup to excluded them from cost calculation and cost activation. as the items increase each year, it is not practical to delete those items. customer tried to stop the item for inventory, purchase process. also tried to use Product lifecycle state, as there is no business process related to cost calculation and cost activation. still could not block the cost calculation and cost activation.
