    SalesParameters                 salesParameters =  SalesParameters::find();

    // Define report and report design to use

    controller.parmReportName(ssrsReportStr(SalesInvoice, Report));

    // Use execution mode appropriate to your situation

    controller.parmExecutionMode(SysOperationExecutionMode::Synchronous);

    // Suppress report dialog

    controller.parmShowDialog(false);

    // Explicitly provide all required parameters

    contract.parmPurchId(_purchId);

    controller.parmReportContract().parmRdpContract(contract);

    // Change print settings as needed

    {

        settings.printMediumType(SRSPrintMediumType::Screen);
