Implementation steps
-
Choose the starting event and owner
Decide which application acts when a return is requested, authorized or notified. Name the operational owner of the return authorization and the team that resolves rejected or ambiguous messages.
-
Keep record IDs connected
Map return authorization, original order and returned item. Confirm qualifiers, code lists, units and date/time meaning against the agreed X12 version and Costco guide. Preserve the source reference alongside any new destination identifier.
-
Test failures before launch
Run the failure cases in the mapping table against realistic return authorization 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 return authorization processing. Give unresolved errors an owner and check the receiving system before approving retries.
Go-live checklist
- An approved 180 sample and the agreed version and partner guide are available.
- The mapping tests pass with realistic return authorization 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 return authorization without processing it twice.
