Implementation steps

  1. Choose the trading account and channel

    Confirm the supplier or customer account, sender and receiver IDs, test environment and current guide for Sam's Club. Compare other Walmart channels before reusing a mapping.

  2. Map records and assign owners

    Start with accounts-receivable or accounts-payable invoice, shipment notice (ASN), purchase-order response. 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 invoice number, purchase order and invoice line. 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.

Which EDI documents are listed for Walmart / Sam's Club?

X12 810 Invoice; X12 856 Ship Notice Manifest; X12 855 Purchase Order Acknowledgment; X12 850 Purchase Order; X12 824 Application Advice. Confirm which documents, directions and versions apply to your account.

How should I choose the Walmart EDI channel?

Sam's Club lists 5 distinct document types. Match the channel to your business unit, account and delivery arrangement; compare the other channel links before choosing a connection. Confirm access and enrollment with the channel owner.

Which identifiers should the Walmart mapping preserve?

For X12 810 Invoice, plan around invoice number, purchase order and invoice line. 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 / Sam's Club EDI?

Reconcile line amounts, allowances, charges and tax to the invoice total. Submit the same invoice twice and verify that it cannot create a second payable. Also test missing responses and recovery after a destination failure. Assign an owner to each failure and obtain partner approval before launch.
