Setting up report users
Use this procedure to add new users, roles, or groups to a report. You can pick users to add from a list of available system users or you can copy a list of users from another report.
Note: Any users that you specify on the report's schedule override the users that
you specify on the report.
Users and roles default into Reporting Services Passed In Request Parameters from the authentication method that you specify during the Framework Services installation. For more information, see Creating a custom group.
