For released documents, it is necessary to reopen them before making changes.

Many users only remember to REOPEN the document after getting the 'error' message triggered from trying to make a change. This requires 'clearing' the error by refreshing F5 and then re-entering the data.

It's a minor thing, but it is frustrating. I would propose that instead of 'erroring' out, the system should prompt the user if the want to 'reopen' the the document and depending on the answer to the 'error message' either 'reopen' the document and apply the change made by the user OR if refused, reject the change and 'refresh' automatically.
