In an incoming student's contact card I see a required field for "enroll date". What purpose does that serve?
The enroll date in Core exists for record keeping purposes and in this case, it will change the users role from Incoming Student to Student. If set to a future academic year, this will give the incoming student role to that record. Once that enroll date hits and/or the future academic year is set as the current year, the user will change to a Student. After that point, however, it is used primarily for record keeping purposes.
