The 943 gives a warehouse advance notice that a supplier is shipping product into the facility, typically a stock transfer into a 3PL. It carries item identifiers, quantities, carrier details, and shipment dates so the warehouse can plan receiving labor and dock capacity before the freight arrives. The warehouse acknowledges receipt of the document with a 997 and, after physically verifying the shipment, typically reports what actually arrived on a 944. Sent by the supplier or manufacturer to the remote warehouse or 3PL that will receive the inbound stock transfer.
When it fires: A supplier releases a replenishment or stock-transfer shipment from its plant or another node to a 3PL warehouse and must tell the facility what is on the truck.
Common 943 rejection causes
- Item identifiers or units of measure that do not match the warehouse's item master, forcing manual receiving.
- Shipment and reference numbers the warehouse cannot echo back on the 944, breaking automated shipped-versus-received matching.
- The 943 arriving after the truck does, so the warehouse receives blind and keys the receipt manually.
- Quantities on the 943 that differ from what is physically delivered, surfacing later as 944 discrepancies and inventory variances.
