How to get the list of articles that are checked out (locked) in OSvC (B2C Service)

Summary:

I am trying to find the right table where I could see all articles that are checked out (locked) by users. Could you please help? I need a list of all articles/answers which are checked out. I found this list via the following steps: Content>Content Type>Find>Lock Status>Locked>Find. But I cannot export this list to Excel because locked articles cannot be selected in this view. Can you please helps?
