Most common alongside 944
The 944 is the warehouse's confirmation of what was physically received on an inbound stock transfer, sent after the goods are checked in. The depositor uses it to post the received quantity into available inventory at that location and to reconcile the receipt against the 943 shipment advice, closing the inbound loop the 943 opened. Suppliers require it because inventory at a 3PL is not sellable until the receipt is confirmed in their own system. Sent by the 3PL or remote warehouse back to the supplier or manufacturer that shipped the stock transfer.
When it fires: An inbound stock-transfer shipment is unloaded, counted, and put away at the warehouse.
Common 944 rejection causes
- Depositor order or reference numbers that do not match the originating 943, so the receipt cannot be tied back to the transfer.
- Received quantities that differ from shipped quantities without an accompanying explanation, leaving the variance unresolved.
- Unit-of-measure conversion errors between warehouse and depositor systems (cases versus eaches) that inflate or deflate on-hand counts.
- WMS-to-ERP integration gaps that delay posting of the receipt, leaving received stock invisible to order-promising systems.
