How to stop deletion of approved leave request before Posting

Hi There,

This seems weird, but when Employee puts a request and Manager approver it. Remember Posting program has not run yet. And employee goes and Delete this request. There is no workflow starting for this, and even Manager do not get any notification.

I tried to workout option "No Deletion to leave request permitted" but somehow that is also not making any difference.

Any thoughts on this..

Thanks a lot.
