Code to clear the cache value / Last used values in SSRS through controller class in AX 2012

public static void main(Args _args)
{
    SrsReportRunController controller  = DASPaymentVoucherController::construct();
    controller.parmArgs(_args);
    switch(_args.menuItemName())
    {
        case menuitemOutputStr(DASReceiptVoucherReport):
        controller.parmReportName(ssrsReportStr(DASPaymentVoucher, ReceiptReport));
        break;
        case menuitemOutputStr(DASPaymentVoucherReport):
        controller.parmReportName(ssrsReportStr(DASPaymentVoucher, Report));
        break;
        case menuitemOutputStr(DASPettyCashVoucherReport):
        controller.parmReportName(ssrsReportStr(DASPaymentVoucher, PettyCashReport));
        break;
    }

    controller.parmShowDialog(true);
    controller.parmLoadFromSysLastValue(false);
    controller.startOperation();
}

Thanks,
