How can I delete all the schedules at once

To delete all the schedules for all students at once, go to Scheduling >> Setup >> Run Scheduler. Check the box beside "Delete Current Schedules" and click on OK. All the dissociated schedules throughout the school shall be deleted at once.

NOTE : This process only works when no transactions have been made in the course periods. That means if attendance and grades have been entered schedules cannot be deleted.
