View Permissions Granted to Application Roles
You can see a list of permissions granted to each user-defined application role as well as permissions granted to the predefined application roles from the Application Roles page.
While you can view, add, and remove permissions for user-defined application roles, each predefined application role includes a fixed set of permissions that you can't change. Specifically, each predefined application role has a set of role-based permissions built into it which aren't listed individually, plus zero or more regular permissions which are listed individually but you can't remove them. For example, the predefined application role BI Consumer has built-in, role-based permissions plus the permission Export Workbook to Document.
