Hi Tami

The suspended field in the reports is related to whether the users is suspended at the site level.

You are wanting a report on users who have their enrolment in a course suspended - using the setting in the enrolment method.

I can't see a report that has this course suspension field included.

Are you using the external unenrolment action to disable course enrolment and remove roles  If this is the case then using a report such as Audience members would show only those users in the audience missing out the users with suspended enrolment
