In order to delete a session, all scheduling information for that session must be removed:

1. Delete all class sections.
2. Delete all course restrictions applying to that session.
3. Delete all course grading information
4. Delete all room restrictions for that Academic Year.
5. Delete all Faculty restrictions for that Academic Year.
6. Check saved scheduling scenario which will maintain scheduling information, and will keep a session from being deleted.
