Hi Joe

That is correct the upload course completions adds a course completion record for the users with course completion by RPL . 

The course completion doesn't add a record for the activity completion - RPL means that they have achieved the same outcomes as the course it doesn't mean they have completed the course activities.

The completion date for the course is the date that is included in the upload file - this will show in the record of Learning. The date for the Certificate can be set to the Course Completion date. 

The Certificate also has a field Print trainer name - to change this to the trainer you want then select the certificate and add the trainer as a locally assigned role. You can also add a locally assigned role to the feedback activity of the past trainer.
