EDI 945: Warehouse Shipping Advice – Explaining EDI

3 min read

What is an EDI 945 document?

An EDI 945 Warehouse Shipping Advice serves as a shipment confirmation. It is sent from the warehouse to inform a supplier that a shipment has taken place and has been sent out to the end-user. 

The EDI 945 is sent out by the warehouse as confirmation that a shipment is out for delivery following the EDI 940 Warehouse Shipping Order, which serves as the original warehouse order requesting for the goods to be shipped. An EDI 940 is different from an EDI 850 Purchase Order, as it goes from the supplier to the warehouse and not from the retailer. Typically, however, the supplier will receive an EDI 850 and then create an EDI 940.

The 945 transaction code provides information about quantities shipped against the quantity ordered. Upon receiving a 945, the supplier will reply with an EDI 997 Functional Acknowledgement so that the warehouse has the document reception on record. The EDI 945 is used to trigger the EDI 856 Advance Ship Notice (ASN), which notifies the retailer in advance about the contents of a pending delivery. Then, the EDI 810 Invoice is sent to the retailer on the supplier’s behalf.
