Summary For a Security Group
If the security framework has been enabled, you can use the Show pages/components authorized for selected group tool to get a summary of pages, reports, and components that members of a security group are authorized to access.
The dialog where security groups are defined has an option to view what users can access if they are members of a particular security group. The Show pages/components authorized for selected group allows you to see all of the pages, components, reports, file extensions, folders, etc. in the Project that the selected Group is authorized to access.
When you click on the hyperlink, the summary dialog is shown. The top list contains all resources the user can access that do not require login. The bottom list shows all files that are only allowed to users who are logged in and are members of the specified group.
