We manage projects with very extended development cycles. I have due dates for milestones, but I want a log that keeps track of every time a due date is changed. Thanks!
So, for example you could set up a child table of date changes and create an entry in the child log table when the due date changes.
Note that you can only trigger an action when the record is edited and the date changes, it will not trigger if the due date changes as a result of a lookup field changing.
