Implementation steps
-
Choose the starting event and owner
Decide which application acts when a buyer places an order. Name the operational owner of the purchase order or sales order and the team that resolves rejected or ambiguous messages.
-
Keep record IDs connected
Map buyer purchase order, order line and trading-party identifiers. Confirm qualifiers, code lists, units and date/time meaning against the agreed X12 version and Walmart guide. Preserve the source reference alongside any new destination identifier.
-
Test failures before launch
Run the failure cases in the mapping table against realistic purchase order or sales order data. Check how the receiving system reports a rejection and how your team corrects it without creating a duplicate.
-
Track every document to completion
Record transport delivery and document validation separately from successful purchase order or sales order processing. Give unresolved errors an owner and check the receiving system before approving retries.
Go-live checklist
- An approved 850 sample and the agreed version and partner guide are available.
- The mapping tests pass with realistic purchase order or sales order data.
- Each submitted document can be traced through delivery, validation and processing in the receiving system.
- Your team knows how to investigate and recover a rejected or timed-out purchase order or sales order without processing it twice.
