EXCHANGE DOC IN FO DOES NOT MATCH ETKT RECORD

This error occurs when you attempt to reissue a ticket (via TTP/EXCH or TTP/RT).

---

Why it happens:

The system compares the old ticket number stored in the FO element (which holds the exchange document info) against the actual ticket record. If there is any discrepancy – a wrong airline code, an incorrect ticket number, or a formatting mistake – the system rejects the transaction.

---

How to fix it:

1. Check the real ticket number – display the e-ticket record using TWD (e.g., TWD/Lx where x is the FA line number, or simply TWDRT to redisplay the current record).
2. Compare the number shown in TWD with the number inside your FO element. Look carefully at both the airline prefix and the numeric part.
3. Correct the FO element – if they don’t match, update the FO line with the exact ticket number that appears in the TWD record.
4. Retry the reissue – after the correction, run the reissue command again (TTP/RT or TTP/EXCH), and it should go through.
