Depending on your process, then yes you could. Just have to ensure your order or workflow actions do what you need to achieve.  You have "delete previous versions" and "delete drafts" actions that can help you achieve this. You could also force check out, then have any edits made and if approved, check it back in which would commit to a new version, otherwise discard check out which essentially deletes any edits. 

Lots to be considered here but depend on what you are really aiming to do.

Hi eHarris,

Im trying to create a doc approval that if rejected it deletes the edits.

have you got a template of what this would look like so far i have this but believe its wrong.

forget the check out and check in was just a test and doesnt work.
