Restricting Enrollment by Course Disqualifier
Restricting enrollment by course disqualifier prevents users from enrolling in a course based upon their previous completion of another course in the system.
For example, if a user attended a live course in 2018, the administrator may not want to allow the learner to attend the 2019 version of the same course.
