I have a project completion date which is initially populated by PMs. But once entered, I want them to seek an approval to change it. I have a process in place for this so that such requests are approved and the new date becomes 'approved completion date', a separate field.
I would like to enforce the discipline. Tried to look at dynamic form functionality. The most I can do is to link to current date. But that still does not work. How to ensure that date is filled once and then becomes read only.
