Our clients wants to be able to unpack a shipment level HU and use the same HU on a different shipment. In standard SAP, once a HU is assigned to shipment the "Delete Assignment" button in VT02N is disabled. If the HU is deleted, the assignment of the shipment number still shows up in VEKP table. Can someone please let me know why the "Delete Assignment" option is disabled in shipment level? Also, is there any workaround to make the HU usable on another shipment?
