Transport loads are useful to load license plates onto trucks. If the license plates have been picked for sales orders with order type "sales order" then a packing slip can be posted for the transport load. If, however, the license plates have been picked for sales orders with order type "item requirement" then the posting of a packing slip on the transport load is not supported. The idea is to support the posting of a packing slip on transport loads for license plates that have been picked for sales orders with order type "item requirement".
