Hi Muhammad
We use course custom fields to add a course owner / manager fields.
My understanding is that you then need to get those added to your report source to then add them as a filter on a report. You can then save a search based on those filters and schedule each saved search to go to a separate course owner.
If you don't want to add a custom field, in some cases we also use a code in the Course ID number field for specific groups of courses. This should already be available on your course completion reports. You could add a code for each course owner or course group.
Let me know if you have any questions
Thanks
Jane
