When
A manually built TST or a manual exchange needs fields filled or corrected. In normal automatic pricing you do not touch TST fields.

Check it worked
TQT shows the updated fields and a consistent total.
Traps
- Manual TST data is the agency's responsibility — a wrong fare or tax becomes a debit memo.
- Taxes marked
O(old) are not collected again;X(new) are. - After
TTK/EXCH, fare codes change (F→R published, I→Y IT, U→W BT) automatically.
