Reverting Changes
Reverting changes will undo any changes you made since you checked out an object.
To revert changes:
1. Go to the object that you want to revert.
2. Select Revert in the Revision Control dashboard zone.
3. In the confirmation dialog box select OK to confirm the action or Cancel to return to the object page.
Once reverted, the object can be checked out by another user.
