X12 945 — Warehouse Shipping Advice
The X12 945 warehouse shipping advice is sent by a warehouse or 3PL to the depositor (seller) to confirm what was actually shipped against a 940 warehouse shipping order.
EDI 945 facts
- GS01 functional ID for 945 groups is SW — warehouse shipping advice is grouped separately from ASN (SH) traffic.
- 945 W12 lines confirm actual shipped quantities a depositor reconciles against the 940 order and downstream 856.
- SignalEDI correlates inbound 945 shipment confirmations to the originating warehouse order in structured JSON.
