hi i create a report in SSRS and i deployed these reports into share point by using URL i want to send parameter value through url....my parameter value is YEAR NUMBER So in my URL i add this &rv:ParamMode=Collapsed&rp:YEAR%20NUMBER=2012 but its shows error like this -- how to solve this Report viewer failed to set the report parameter defaults for this report. Select new default parameter values from the tool pane. Parameter 'YEAR NUMBER' does not exist on this report

how were you able to create a parameter with name "YEAR NUMBER". With RB 3.0 and SSRS in 2008r2 a paramter name must begin with a letter and have letters, numbers, an underscore (_), and no spaces. you can find more infromation about this here http://technet.microsoft.com/en-us/library/dd220464(v=sql.105).aspx

ya thanks for ur reply..i got solution parameter name is like YEAR NUMBER,but in promt YEAR_NUMBER..now its work good
