Lock courses

You can lock courses to disable their accidental schedule changes in Weeks and Timetables window. You can lock and unlock a course by clicking [Ctrl+U] or the corresponding button. In selection Tools|Lock courses you can lock and unlock several courses at once and set locks by components. Note that locking locks all lectures of a selected course.

Locking of courses prevents the user from making accidentally mistakes in interactive and automatic timetabling, or when allocating lectures to weeks. Lock those courses you want to freeze either temporarily or permanently. Another way to prevent user from mistakes is to set Bookings to some of the free cells in timetables. This prevents from assigning lectures in undesired slots.
