did you ever get this resolved? I am having a similar issue below is a sample of my code but the viewer still displays
static void SR_SaveReportToPDFFromController(Args _args)
{
SalesPackingSlipController SalesPackingSlipController;
SalesPackingSlipContract SalesPackingSlipContract;
salesTable salesTable;
Args args = new Args();
SrsReportRunImpl srsReportRun;
CustPackingSlipJour CustPackingSlipJour;
ReportName reportName = "SalesPackingSlip.Report";
str invoiceFileName;
;
select firstOnly CustPackingSlipJour
where CustPackingSlipJour.SalesId == 'SO011043';
salesTable = SalesTable::find(CustPackingSlipJour.SalesId);
args.record(CustPackingSlipJour);
SalesPackingSlipController = new SalesPackingSlipController();
SalesPackingSlipController.parmReportName(reportName);
infolog.setInfoLogLevel(SysInfoLogLevel::None);
SalesPackingSlipContract = SalesPackingSlipController.parmReportContract().parmRdpContract();
SalesPackingSlipContract.parmRecordId(CustPackingSlipJour.RecId); // Record id must be passed otherwise the report will be empty
SalesPackingSlipController.parmArgs(args);
srsReportRun = SalesPackingSlipController.parmReportRun() as SrsReportRunImpl;
SalesPackingSlipController.run();
SalesPackingSlipController.parmReportRun(srsReportRun);
SalesPackingSlipController.parmReportContract().parmPrintSettings().printMediumType(SRSPrintMediumType::File);
SalesPackingSlipController.parmReportContract().parmPrintSettings().overwriteFile(true);
SalesPackingSlipController.parmReportContract().parmPrintSettings().fileFormat(SRSReportFileFormat::PDF);
invoiceFileName = "AX_" + CustPackingSlipJour.SalesId + ".pdf";
SalesPackingSlipController.parmReportContract().parmPrintSettings().fileName('c:\\lori\\' + invoiceFileName);
SalesPackingSlipController.runReport();
infolog.setInfoLogLevel(SysInfoLogLevel::All);
}
