Lock Student Schedules
If you manually adjusted students' course requests and are satisfied with the resulting schedules, you can effectively lock those students' schedules before reloading by excluding them from the student selection before reloading. That way, only the selected students are included in the load.
If one of the students in the selection has an association with another student, such as a Student Avoid constraint, the schedule of the "other" student not included in the selection may be affected by the load process.
