Hi George,
Unfortunately I can't send a screenshot as I had to remove the completion settings using the delete the existing data as the outcome was eratic and causing havoc with my completion settings however I'll try and explain-
I have a Basic Life Support course and the completions settings were set so that the learner could complete 'Any' of the selected activies OR 'Any' of two other courses (Intermediate Life Support or Advanced Life Support). The outcome being if the learner completed one of the Basic Life Support activities then the record updated as you would expect however if they updated via either of the other courses then the date bore no resemblance to the date the course was actually completed, not sure if it was displaying when the CRON picked the information up - all very bizarre, I would expect the dates for the completion of Basic Life Support to match the date of completion of the other course, not a few days later (the other option is that it could be picking up the date when the course status changes to 'Fully attended' as this can be a few days after the course has actually taken place?).
Hope this gives you a little bit more to go on.
Thanks - Steph
