Hi George, 

thank you for replying. 

From what I know, we will be moving to Totara 13, but as you know it won't happen for some time. I was looking for a solution in the meantime. I saw that there is a Course completion editor in Totara 12, but was not sure if that option can be added to the version we have. Somehow I can amend status for a learner from Complete to In progress, but not to a degree that as if the learner never enrolled to the course, which is what I would need at the moment. 

Going forward, if we kind of mark all the false enrollments in CSV file for example, is it possible to delete them later after upgrade via bulk?  

Best, 

Vladimir
