Data retrieval failed for the subreport in RDLC Reporting

Question

Hi All,

I have created nested reports using RDLC with sub report.

On local machine its working fine. but when I uploaded it on test server it showing error for child report. Error message is - 

Data retrieval failed for the subreport, 'SubReportName', located at: xxx.yyy.SubReportName.rdlc. Please check the log files for more information.

The code for sub report -

void SubReportQuestionHeadProcessing(object sender, SubreportProcessingEventArgs e)

{

switch (e.ReportPath)

{

case "SubRptQuestionHeads":

{

DataTable ldtQA = new DataTable();

int MonitoringDataID = Convert.ToInt32(e.Parameters["MonitoringDataID"].Values[0]);

int OrganizationId = Convert.ToInt32(e.Parameters["OrganizationId"].Values[0]);

int TemplateId = Convert.ToInt32(e.Parameters["TemplateId"].Values[0]);

int HeadID = Convert.ToInt32(e.Parameters["HeadID"].Values[0]);

String RowNumber = Convert.ToString(e.Parameters["RowNumber"].Values[0]);

ldtQA = Anidan.BLL.MonitoringData.GetMonitoringReportDataQuestionAnswersForMAStudy(MonitoringDataID, OrganizationId, TemplateId, HeadID, RowNumber);

e.DataSources.Add(new ReportDataSource("DS_QuestionAnswers", ldtQA));

break;

}

}

}

 

 

Please suggest the solutions if any one have.

Thanks in advance..
