For example, instead of setting a trigger to mark a user as overdue on January 1st, 2030, the workflow trigger would be set to mark a user as overdue on the Due Date. The Due Date can then be set to different values for different enrolments, i.e. Course A may have a Due Date of January 1st, 2030, but Course B might be a different date. In this way, the same workflow rules can be used for different enrolments.
