If you turn Autocommit mode off, the Rollback and Commit commands in the Record menu are enabled. You can now make changes to several records, and then decide whether to commit (accept) or rollback (undo) all of these changes. Choose the appropriate command from the Record menu.
If accessing an XDB Server version 4.x or lower, you must turn on the Backward Log using the Options utility. If the Backward Log is not on, rollback commands will have no effect.
