Currently, if you have the Course set in
  1. Academics > scheduling > Requests and schedules
  2. Departments and Courses
  3. Search the Course Name and click the editing pencil

Click the Grading Tab If the  "How should this course appear on transcripts ?"Abbreviation: is being used then the Course will display on the Transcript as the Abbreviation and the Courses in Progress will have the actual Course Titles

For example:

If in Departments and courses you have the Abbreviation as  AP-BC Calc but Calculus II AP on the Course Title then it will display as Calculus II AP on the Courses in Progress and AP-BC Calc where the Course Title is for the Grades that have been recorded.
