update a batch

Moving transactions within a batch to the database. Most information that is updated to the database is not autopriceable or received by subscribers unless it is filed in GFS. Also called making a batch public (Release action).

Records in batch processing that do not pass update. The update step applies the fares to the master file. If there are difficulties, then the fare will not be applied to the master file.

Update errors occur, for example, when a carrier tries to increase a fare that does not exist, cancel a fare that is already canceled, or add a new fare that already exists.
