Undoing a User Checkout
If a user in your project or program has an object checked out, you can undo the checkout, reverting to the last modified iteration of the object. This is useful in situations where the user who had the object checked out has left the company, or if they are out of the office when the checked out object is needed.
If you know the object or objects for which you want to undo the checkout, you can perform the undo checkout action on an object from either the Folders page of your project or program, or from the information page for the checked out object.
