Students not populated into a course (from iSAMS). How can I add student users to courses?

[LauraMurphy]

Head office has populated all courses on canvas with the students in relevant subjects from iSAMS. 

However, some classes have not populated. 

How can I add student users to courses? Or indeed check the synch with iSAMS. 

I am just a school level admin so might not have access right potentially.

I would recommend checking in with your Head Office to report this issue.  Since it sounds like they handle the sync, they should be able to investigate the issues and follow-up with the vendor if necessary about the missing classes/enrollments.  Due to variability in how schools handle course creation/enrollments, it would be best to check with them first to ensure you are following the appropriate set-up.  Often courses and enrollments that are created from a sync with another system need them to be fully managed by the sync to work as expected, so manual enrollments may not be an option.
