When running a report, users may receive the error:
The section could not be loaded. The permissions granted to user '[WINDOWSUSER]' are insufficient for performing this operation.
This occurs when the user does not have sufficient rights in Microsoft SQL Reporting Services.
Verify which groups have rights to the report through the Reporting Services site and confirm in User Management for the domain that the user is in the appropriate group.
This can be done through Microsoft Reporting Services, or through the application itself. In order to grant permissions through the application, please follow the steps below:
1. Go to Reports 2. Select Report explorer 3. Filter down to the report for which you received the error 4. Right-click the report and select Properties 5. Select the Permissions tab and verify that the user or users group has a minimum of "Browser" rights
