EDI 943 - Warehouse Stock Transfer Shipping Advice

What is the EDI 943? The EDI 943 transaction set, also called the Warehouse Stock Transfer Shipment Advice, is used by a supplier to inform a warehouse of a shipment’s contents. This transaction is primarily used in a 3PL context where products are being moved from the supplier’s facility to a warehouse.

The EDI 943 allows the warehouse to prepare for incoming goods by providing details about the products in the shipment. This enables better planning and allocation of warehouse resources.
