How To Pass Parameters In Url For A Report Published In Reportserver (report Built On Stocked Procedure) ?

Hi,



I have created a report with the report server project template.

the report is created from stoked procedure having defaut input parameters.

With visual studio, i publish my report on reportserver. whenever i access to my report on this url :

http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fReport+Project4%2fReport4&rs:Command=Render. the created report is with the default parameters.



I would like to know if i can transmet parameters for the stocked procedure to build the report with the request i want.


I tried to put parameter directly in the url in this way

http://localhost/ReportServer/Pages/ReportViewer.aspx?%2fReport+Project4%2fReport4&rs:Command=Render&@region='toto'

but without success.

my error message is that one

An attempt was made to set a report parameter '@region' that is not defined in this report. (rsUnknownReportParameter)





My stocked procedure is :

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
go
ALTER procedure [dbo].[akli] @region varchar ='m'
as
select * from dbo.Report2 where region=@region

The request used to buid the report ?
DECLARE @region varchar
EXECUTE dbo.akli @region


What is wrong in that ?

Thanks for your help.
