If we can add a checkbox if External Learner has paid the money (Payment has been done outside the system but it is used to record into the Oracle)

To see if the external user has paid for the course, go to Edit Assignment through DFF at the course level and follow the instructions below: My Client Group > Select Course > Select Learner > Click Edit Assignment. So, the learner can see if the course is given to an external learner or not. If it is, then the learner paid for that course, as it can be mapped in front of each learner.
