From the Application Users page or the Users tab of a system role record, when you select a user's name, the application user record for that user appears. The application user record contains information about all the items to which the user has access, a combination of the items included in all the roles to which the user belongs.
From the Application Users page, you can access and view records for your users. Each record contains a System Roles tab that shows each role the user is assigned to, and a Tasks tab that displays each task the user can access. From the System Roles tab, you can add and remove users from a system role.
Note: The system roles and corresponding tasks on the application user record are view only. They display to help you better understand how roles are set up.
