When the "issue credit" button is used, if a mark has already been posted for the same course, it doesn't allow a new grade to be posted, but instead tries to overwrite the originally posted grade for the same course number (linked by SQ). With Independent Study students, they many times boomerang back to the same course for making up units. We need to be able to add new records to GRD/HIS instead of overwriting them when using the "Issue Credit" button in our school using Alt Ed Scheduling.
