For a supervisor to report actual work hours by work order number, the work order typically needs to be in a status where work can be actively tracked or has been completed. The 'INPRG' status indicates that the work is in progress, allowing for real-time tracking of actual work hours. Similarly, the 'COMPLETE' status indicates that the work has been finished, and the total actual work hours can be reported. Therefore, these two statuses (INPRG and COMPLETE) are appropriate for reporting actual work hours.
