Naming The SSRS Report Name based on the Parameters Passed I want to save my SSRS Report Based on the Parameters Passed. i.e. Am passing P1 And P2 as parameters so I want my SSRS 
Report name as P1_P2_ReportName.Xtension.

Any suggestions?
What you are asking is to be able to create a report name dynamically, which is not something that can be programmed, on download, say, from Report Manager. You can (although I've never tested this) possibly do this through a  subscription using @ParameterName @ReportName. citation from msdn It's about the best you can do for now, and there's a link on the citation that allows for this feature to be voted up.
