Implementation steps

  1. Choose the trading account and channel

    Choose among Walmart US (Goods for Resale), Walmart Canada, Sam's Club, Walmart (Goods Not For Resale) and the other channels listed below. Confirm the business unit and account before copying a mapping from another channel.

  2. Map records and assign owners

    Start with application validation result, shipment notice (ASN), business message. For each document, assign the source system, destination record, stable identifiers and person responsible for exceptions. Agree whether a change updates an existing record or creates a new event.

  3. Test a complete exchange

    Run a successful exchange and the failure cases in the mapping table. Track delivery, document validation and processing in your business system separately. Agree on the Walmart production handoff and save the results of each approved test.

  4. Check results after launch

    Match records between systems using original document reference, error location and response status. Assign an owner to missing responses, duplicates and rejected records. Test recovery before enabling automatic retries.

Go-live checklist

  • The required X12 documents, versions and sample files are agreed.
  • Sender and receiver IDs, test connections and production connections are agreed with the channel owner.
  • Delivery receipts, document validation and business responses have monitoring and a named owner.
  • Tests cover duplicates, partial processing and reconciliation with realistic business records.

FAQ

Walmart EDI questions

Which EDI documents are listed for Walmart?

X12 824 Application Advice; X12 856 Ship Notice Manifest; X12 864 Text Message; X12 855 Purchase Order Acknowledgment; X12 810 Invoice; X12 850 Purchase Order; X12 816 Organizational Relationships; additional documents are shown in the mapping plan. Confirm which documents, directions and versions apply to your account.

How should I choose the Walmart EDI channel?

The directory lists 8 channels for Walmart, including Walmart US (Goods for Resale), Walmart Canada, Sam's Club, Walmart (Goods Not For Resale). Match the channel to your actual trading relationship and compare its document list before reusing a mapping.

Which identifiers should the Walmart mapping preserve?

For X12 824 Application Advice, plan around original document reference, error location and response status. For X12 856 Ship Notice Manifest, use shipment, order, package and item references. Use the partner guide to locate these values and check their allowed formats.

Does a successful EDI receipt mean Walmart accepted the business document?

Track delivery, document validation and business processing separately. An AS2 message disposition notification (MDN) confirms transport receipt; an X12 997 or 999 reports technical validation. Use the agreed business response or reconciliation report to confirm that the order, shipment or invoice was processed.

What should be tested before launching Walmart EDI?

Return an error for one line and associate it with that line rather than rejecting unrelated records. Keep application acceptance distinct from transport receipt and syntax acknowledgment. Also test missing responses and recovery after a destination failure. Assign an owner to each failure and obtain partner approval before launch.
