T/C Lock (Tariff/Carrier Lock) can be used when releasing a batch. If this field is selected, release processing on the entire batch will be stopped if any transaction in the batch encounters an application error. All subsequent batches for the same tariff and carrier will not process until the T/C lock is released.

If this field is not selected, any transaction that can pass application edits will be applied to the database while any transaction that encounters an application error will be rejected (commonly called a “bounce out”).

A batch can only be released once. If the T/C Lock Requested field is not selected and some transactions in the batch are rejected (bounced-out), they cannot be corrected in the same batch. They must be copied or moved to a new batch. After the errors are corrected, the new batch must then be released.
