The delivery feedback is a report to the WMS about changes to the status of a delivery. Within the delivery order processing in the WMS, different statuses can be carried forward and submitted to the ERP system to initiate follow-up processes (e.g. invoice printing). Possible statuses are: “order picking completed”, “packing completed”, “loading completed”. Usually, booking of outgoing goods takes place when the transport unit leaves the warehouse site. This is reported back to the ERP system, synchronising the stock situations in both systems.
