What is an EDI 943?

The EDI 943 Warehouse Stock Transfer Shipment Advice is an advance ship notice to a remote warehouse indicating the transfer shipment has been made from the manufacturer. EDI 943 is also utilized by manufacturers in order to authorize a warehouse to accept a return from a customer.

How to use an EDI 943?
 

The EDI 943 Warehouse Stock Transfer Shipment Advice is sent by the warehouse sending the material to the receiving warehouse. After the destination warehouse receives the EDI 943, an EDI 997 (Functional Acknowledgement) is sent back from the receiver to indicate that the EDI 943 was successfully received.

Example EDI 943 transaction exchange:

Because the EDI 943 is sent in response to an EDI 940, you can start to understand the traditional order for this data exchange.

Here is an example of where the EDI 943 fits in within the transaction series:

1. First, an EDI 940 Warehouse Shipping Oder is sent by a supplier to a 3PL provider to formally request shipment of goods from a remote warehouse to the supplier's (buyer's) location
2. The third-party logistics provider sends the EDI 943 as an advanced shipment notice to a remote warehouse, informing the supplier that a transfer shipment has been made from the manufacturer. 
3. Finally, the series is completed after an EDI 945 Warehouse Shipping Advice transaction is sent to provide confirmation of a shipment. The EDI 945 informs the trading partner a shipment was made.
