How can I see detailed information about learner activity?

I am a Learning Admin. After taking a service call today, I found that our leaders have the ability to withdraw their direct reports from required training. Even those that are tied to regulatory standards. I've searched the Learning Assignment page for a way to view who withdrew a person, but cannot seem to find the detailed information.

When I click on the Assignment Number, I get a message stating "You don't have access to this learning record". Is there a profile or security setting that needs to be updated for me to see this data?

Can I run a report to see how many learners have been withdrawn from required learning by someone other than me, or something other than Learning Initiative Reconciliation?
