我可以通过 API 删除 Acumatica 中的文件吗？

找到了如何从 Acumatica 中删除文件以及如何保存现有文件的新版本的示例！下面的实现保存了一个新版本，但注释掉了删除方法。因为我将它构建到我的报告生成过程中，所以我以后不会通过 API 删除报告，但是很容易将删除转换为可由 API 调用的操作。

private IEnumerable ExportReport(PXAdapter adapter, string reportID, Dictionary<String, String> parameters)
    {
        //Press save if the SO is not completed 
        if (Base.Document.Current.Completed == false)
        {
            Base.Save.Press();
        }

        PX.SM.FileInfo file = null;
        using (Report report = PXReportTools.LoadReport(reportID, null))
        {
            if (report == null)
            {
                throw new Exception("Unable to access Acumatica report writer for specified report : " + reportID);
            }

            PXReportTools.InitReportParameters(report, parameters, PXSettingProvider.Instance.Default);
            ReportNode reportNode = ReportProcessor.ProcessReport(report);
            IRenderFilter renderFilter = ReportProcessor.GetRenderer(ReportProcessor.FilterPdf);

            //Generate the PDF
            byte[] data = PX.Reports.Mail.Message.GenerateReport(reportNode, ReportProcessor.FilterPdf).First();
            file = new PX.SM.FileInfo(reportNode.ExportFileName + ".pdf", null, data);

            //Save the PDF to the SO
            UploadFileMaintenance graph = new UploadFileMaintenance();

            //Check to see if a file with this name already exists                
            Guid[] files = PXNoteAttribute.GetFileNotes(Base.Document.Cache, Base.Document.Current);
            foreach (Guid fileID in files)
            {
                FileInfo existingFile = graph.GetFileWithNoData(fileID);
                if (existingFile.Name == reportNode.ExportFileName + ".pdf")
                {
                    //If we later decide we want to delete previous versions instead of saving them, this can be changed to 
                    //UploadFileMaintenance.DeleteFile(existingFile.UID);
                    //But in the meantime, for history purposes, set the UID of the new file to that of the existing file so we can save it as a new version.
                    file.UID = existingFile.UID;
                }
            }

            //Save the file with the setting to create a new version if one already exists based on the UID                          
            graph.SaveFile(file, FileExistsAction.CreateVersion);  
            //Save the note attribute so we can find it again.              
            PXNoteAttribute.AttachFile(Base.Document.Cache, Base.Document.Current, file);
        }

        //Return the info on the file
        return adapter.Get();
    }
