A simple despatch message is provided in the image below. It starts with some header information describing the delivery, it contains a description of who is sending the delivery, who is making the delivery and to who the delivery is sent. There is also some general shipment information provided, such as the estimated delivery period. The example below then contains three different order lines. The example shows three despatch lines describing the delivery of items. Despatch line number one delivers 2 boxes with dishwashers, the second despatch line despatches an item from the same order, but a different orderline, in that case a box containing an oven. The last despatch line describes some cleaning agent, ordered in a different order. The bottles of cleaning agent are stored in 3 boxes, on one pallet. In the message specification this may be described as pallet being the transport handling unit, used to handle 3 packages (being the boxes) which contain the 150 bottles of cleaning agent. This does assume that every bottle of cleaning agents is a single item. For every product a traceID is provided, matching the transport handling unit to, for example, a barcode.
