The Report Access tab of the Login Properties window allows you to limit user access to specific reports. Use this tab if your environment requires permissions settings that tightly control report access by limiting user access to only be able to see the selected reports. For example, you can deny access to the Configuration Reports by default, but grant a specific login access to those specific Reports.
As an Administrator select the Login on which you want to set permissions, and then select the appropriate report permissions for that user.
Your selections are applied along with any default permissions you set when you registered the corresponding SQL Server instance.
These updates are for the Windows Console only, and are not available via the Web Console or the SSRS reports.
