 One of our clients recently reported the following error while the user tries to open the Project Card.   “ The Project Is Being edited By another User, please select another project/contract number ”  We checked all the users and no one was accessing this project. Then we found there are invalid entries under “PA Proj Contr Activity Master table”.
