Multiple report execution

Hi,

I am trying to execute multiple designs of the same report at the same time. The controller class reads like:

class MyReportController extends SrsReportRunController

public static client void main(Args _args)
{
    MyReportController controller = new MyReportController();
    ReportDesign labelSize;
    ;
    
    labelSize = _args.parmEnum();

    if(labelSize == ReportDesign::SmallBox)
        controller.parmReportName(#ReportName_S);
    else if(labelSize == ReportDesign::Normal)
        controller.parmReportName(#ReportName_M);
    controller.parmData(_args.record());
    controller.parmRecId(_args.record().RecId);
    //controller.parmReportContract().parmPrintSettings().printMediumType(SRSPrintMediumType::Screen);
    controller.parmExecutionMode(SysOperationExecutionMode::ReliableAsynchronous);
    controller.parmShowDialog(false);
    controller.startOperation();
}

and the method calling the menuitem of the controller class is:

ReportDesignEnum ReportDesign;
;
args.record(MyTable_1);
ReportDesign = ReportDesign::SmallBox;
args.parmEnumType(enumnum(ReportDesign));
new MenuFunction(menuItemOutputStr(MyController), MenuItemType::Output).run(args);

args.record(MyTable_1);
ReportDesign = ReportDesign::Normal;
args.parmEnumType(enumnum(ReportDesign));
new MenuFunction(menuItemOutputStr(MyController), MenuItemType::Output).run(args);

However, no report design is seen on the screen.

The reports execute one after the other if I comment the execution-mode.

What could I be doing wrong?
