I'm trying to pass a parameter via the url to SSRS and it appears not to work!
I'm trying to pass a userId (string) via the url which will be passed to the database and used by the query.
base url: http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport
tried this but it doesn't work: http://blah/Reports/Pages/Report.aspx?ItemPath=MyReport&UserId=fred
Any ideas
