By default, Reporting Services reports output with two headers. When these headers are not useful or take up too much space in the page design, you can control it by changing the URL through which the report is run.

SSRS reports include two headers, Subscription and Toolbar.
To suppress the Subscription header
When you publish a report, Report Manager generates a URL that includes the Subscription header:
http://localhost/Reports/Pages/Report.aspx?ItemPath=%2fReports+for+the+ProgressCRM+Dashboard%2fDonor+status+chart
To run the report without the Subscription header, call a different command, formed like this:
http://localhost/reportserver?%2fReports+for+the+ProgressCRM+Dashboard%2fDonor+status+chart&rs:Command=Render
To suppress the Toolbar header
To run the report with the Toolbar header, which includes parameter and export options, add &rc:Toolbar=false to the end:
http://localhost/reportserver?%2fReports+for+the+ProgressCRM+Dashboard%2fDonor+status+chart&rs:Command=Render&rc:Toolbar=false
