Generate "Check Form with Remittance" Report(ap641000.rpx) Programmatically

Hi all,

I want to generate “Check form with remittance”(ap641000.rpx) Report Programmatically. But in the usual way, I was unable to do that as it has no key parameters. 

I used to do report generation in the following way. But I can not apply this approach here as there are no key parameters here. Is there any alternative approach of doing this?

Dictionary<String, String> parameters = new Dictionary<String, String>();
parameters["DocType"] = apInvoice.DocType;
parameters["RefNbr"]  = apInvoice.RefNbr;

//Report Processing
PXReportSettings settings = new PXReportSettings("MA105000");

PX.Reports.Controls.Report report = ReportLoader.CheckIfNull(nameof(ReportLoader)).LoadReport("MA105000", null);
                                 ReportLoader.InitReportParameters(report, parameters, settings, false);

PX.Reports.Data.ReportNode reportNode = ReportDataBinder.CheckIfNull(nameof(ReportDataBinder)).ProcessReportDataBinding(report);

byte[] data = PX.Reports.Mail.Message.GenerateReport(reportNode, RenderType.FilterPdf).First();

string filename = "Test Report";

PX.SM.FileInfo file = new PX.SM.FileInfo(filename, null, data);

Additionally, there are few filters as below. But how can we pass values there?
