As explained in the preceding chapters, locks can be entered in different ways in Untis. You can obtain a summary of all lessons locked in the school data by opening the "Lessons | Locked Lessons" window. The list of rows contains all the lessons which are currently locked from being moved, which Untis (timetable optimisation) is not allowed to move. The columns indicate the level or the master data element causing the lock. You can use the <Delete> button to remove individual locks.
