The Rollback Record Changes capability allows the user to undo the last saved changes to a record – to roll it back to the previous version. Rolling back the record again will cause the record to undo the last change (which was to roll back the record) and the record will revert to the state it was in before the rollbacks were done.
To roll back changes to a record:
Note that rolling back the state of the record again causes the record's attributes to revert to their values prior to the last change, in effect, reversing the first rollback.
