I have a service that batches SSRS reports by making calls to the RSExecution web service.

I am having an issue with reports that contain cascading parameters, it seems that I am unable to successfully set a parameter value for a cascading parameter.

Any attempt at running the report programatically results in a ReportParameterValueNotSetException, even though I am sending the report parameter in via theReportExecutionService.SetExecutionParameters method

 

Ideas or tips?
