ssrs 2008 missing parameter value

  • 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?

  • Is the parameter being passed to a subreport? If so do you have the parameter defined in the subreport properties on the main report?

  • Do you have anything configured under report properties for available values and default values that might cause this behavior?

  • Verify the parameter in each of your queries. Beware that parameters are cap sensitive and you could be running into it passing to not all of your queries.
