When running the Match Active Applications and Enrollments plug-in for records identified by the Find Unlinked Active Applications and Enrollments plug-in, the exception Active application is not an application/enrollment may occur for some students.
Alternative Solution: 1. Run Enroll applications for the records that are producing the exception. Make sure that the application that should be connected to an enrollment is marked active. 2. Update the new enrollment that is now linked to the application with the correct information. The old enrollment can be deleted if desired.
