Cartonization Planning During Warehouse Order Creation
You can use this function of automatic cartonization planning to have the system create planned shipping handling units (PSHUs) for pick-warehouse tasks during warehouse order creation. The system uses the PSHUs as templates to create shipping HUs during either picking or packing.
