This electronic transaction set validates completed shipments while providing detailed information necessary for inventory reconciliation and downstream processes.

Understanding the EDI 945 transaction becomes crucial when managing complex supply chain relationships involving remote warehouses and external fulfillment centers. The document creates transparency in shipping operations while maintaining accurate records of product movements throughout the distribution network.

What Is the EDI 945 Transaction Set?

The EDI 945 functions as an electronic shipping confirmation that warehouses and 3PL providers transmit to suppliers upon completing order fulfillment. This standardized document communicates essential shipment details and serves as official confirmation that products have departed the warehouse facility.

EDI 945 in the Supply Chain Communication Flow

The warehouse shipping advice operates within a structured sequence of EDI transactions:

Order Initiation:

• Supplier transmits EDI 940 warehouse shipping order to 3PL

• Document specifies products, quantities, and shipping requirements

• Instructions include destination details and special handling needs

Processing Confirmation:

• 3PL acknowledges receipt with EDI 997 functional acknowledgment

• Warehouse begins order preparation and fulfillment activities

• Internal systems update to reflect incoming shipping requests

Shipment Completion:

• EDI 945 warehouse shipping advice is generated upon product departure

• Document contains actual shipped quantities and carrier information

• Supplier receives confirmation of completed fulfillment activities

Downstream Activities:

• Supplier processes EDI 945 data for inventory updates

• Advanced ship notice (EDI 856) may be generated for end customers

• Invoice creation and payment processing can be initiated

This systematic approach maintains clear documentation while supporting automated business processes.
