In an SSRS 2008 R2 existing report, I am passing a new parameter called 'SchoolYear' to an existing report. I obtain the value for SchoolYear from the following statement =(Fields!SchoolYear.Value) that is used against the dataset DS_Main.
I am getting the error message, "The 'SchoolYear' parameter is missing a value" when the called SSRS report is running. When I 'hard-code' the school year value in the called ssrs report, the called report runs.
When I run the sql in the dataset DS_Main, I get all kinds of rows and all the rows contains data.
Thus I do not know how the 'SchoolYear' parameter is not passing a value. Would you tell me what I can do to determine
what is causding this problem?
