When an Academic Year is over and a Course should no longer be modified, it is advisable to lock these Courses. No changes can be made to a Course that has been locked.
This is a very straightforward process. All that needs to be done is to click the Lock icon as shown above. As you can see below, the course has now been locked.
IMPORTANT NOTE: Locked courses can still be rolled over.
Clicking on the Course again to review the details indicates every Course-related detail is now in read-only mode and cannot be modified as long as the Course is locked.
