940 Warehouse Shipping Order

Functional Group OW

X12M Supply Chain Subcommittee

This standard provides the format and establishes the data contents of the warehouse shipping order transaction set. This transaction set is used to enable the depositor to advise the warehouse to make a shipment.

What is an EDI 940?

An EDI 940 Warehouse Shipping Order communicates shipping requests from a seller to a warehouse. It contains information about order identification (W05 segment), carrier details (TD3 segment) and line item details (G69 segment).

How is an EDI 940 used?

For example, Seller A leverages a third-party logistics warehouse to fulfill their orders. After a customer buys their product, Seller A sends Warehouse B an EDI 940 Warehouse Shipping Order to fulfill the order. After the order has been fulfilled, Warehouse B will respond to Seller A with an EDI 945 Warehouse Shipping Advice to confirm the fulfillment and provide shipment details.
