Scheduled Tasks

Hello,

I am looking for more information on CourseMill (version 7) Scheduled Tasks:

https://www.trivantis.com/help/CourseMill/7/en/SuppGuide/Content/CM7_scheduledtasks.html

The details in this document are very vague.  We recently registered several curriculums to students.  When the students reported the curriculums not showing, we ran the DBMaintSchedule task, and this fixed the issue.  I'd like to know what the underlying processes behind DBMaintSchedule are, and when and how to use these tasks.

Thanks,

Benjamin
