Choose the starting event and owner
Decide which application acts when routing details are issued in response to a shipment need. Name the operational owner of the routing instruction and the team that resolves rejected or ambiguous messages.
-
Keep record IDs connected
Map routing reference, order and shipment. Confirm qualifiers, code lists, units and date/time meaning against the agreed X12 version and AT&T Inc. guide. Preserve the source reference alongside any new destination identifier.
-
Test failures before launch
Run the failure cases in the mapping table against realistic routing instruction 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 routing instruction processing. Give unresolved errors an owner and check the receiving system before approving retries.
