I want to display the output of an SSRS report in an IFrame of another application. I set the source to something like this:
http://SERVERNAME.domain.com/ReportS
You can force the report server to get a new report in every request by clearing the session.
Just add the following to the URL rs:ClearSession=true
It would be implemented in your URL like that:
http://SERVERNAME.domain.com/ReportServer?%2fTBI_MSCRM%2fCustomReports%2f%7bdafdbed0-1e96-
e211-a5da-001d0967e0fc%7d&rs:Command=Render
&rs:ClearSession=true&rc:Toolbar=false
Clear session:
A value of true directs the report server to remove a report from the report session. All report instances associated with an authenticated user are removed from the report session. (A report instance is defined as the same report run multiple times with different report parameter values.) The default value is false.
