When an RTO acquits, or completes, a Contract Program of Study (CPS) in TAMS, you must also uncheck the RAPT reporting option for EACH PowerPro course linked to that specific CPS
Otherwise every unit enrolment in RAPT that is related to that CPS will produce an error in TAMS
To do this, via Accredited Courses, open the desired course and then click on the RAPT tab
Uncheck the 'Report this Course' check box and then click on Save
