Locking a run protects a run in the same manner as published runs, except run results are not published to crewmembers. A locked run cannot be deleted or invalidated.
To lock a run:
Switch to the Run Manager tab.
Switch to the Completed tab, if it isn’t currently displayed.
Select the completed run that you want to lock. Only valid runs can be locked.
Click the Set State button. A menu opens with three options: <Clear>, Locked, and Published.
Select the Locked list item. The N-PBS Scheduler asks you to confirm that you want to lock the selected run.
Click the OK button. The N-PBS Scheduler locks the run and Locked is displayed in the State column.
