Most common alongside 945

The 945 is the warehouse's confirmation that a shipment ordered on a 940 has left the facility, reporting what actually shipped: quantities, item identifiers, carrier, bill of lading, and dates. The depositor uses it to relieve inventory, reconcile shipped versus ordered quantities, and drive customer-facing documents such as the invoice. It is the control point that keeps the seller's books aligned with what the 3PL physically did. Sent by the 3PL or warehouse back to the supplier, manufacturer, or seller whose goods it ships.

When it fires: The warehouse completes picking, packing, and carrier handoff for a 940-directed order and the freight leaves the dock.

Common 945 rejection causes
  • Shipped quantities or item identifiers that do not align with the originating 940, causing inventory and billing discrepancies.
  • Missing bill of lading or tracking numbers, which blocks downstream shipment visibility.
  • Missing mandatory segments, invalid segment sequence, or version mismatches that cause rejection at the depositor's translator.
  • Missing lot or serial numbers on traceable product, compromising traceability obligations.
