Acumatica 将图像上载到序列号

我在InItemLotserial表中创建了一个自定义NOTEID字段，用于上传自定义页面中每个序列号的图像。它工作正常，没有任何问题

我已经写了一个处理页面来更新现有序列号的图像

protected void AttachImage(InfoINItemLotSerialImport row, INItemLotSerial ser, InventoryItem itm)
    {
        string imageurl = row.ImageSourceUrl;
        string imageType = row.ImageType;
        string sRetVal = string.Empty;
        if (itm != null)
        {
            if (ser != null)
            {
                try
                {
                    WebClient wc = new WebClient();
                    byte[] buffer = wc.DownloadData(imageurl);
                    //MemoryStream ms = new MemoryStream(bytes);

                    string fileName = Path.GetFileName(imageurl);
                    fileName = string.Format("Serial Number attribute ({0} {1})\\{2}", itm.InventoryID, ser.LotSerialNbr, fileName);
                    PX.SM.FileInfo fileinfo = null;
                    PX.SM.UploadFileMaintenance filegraph = PXGraph.CreateInstance<PX.SM.UploadFileMaintenance>();
                    fileinfo = new PX.SM.FileInfo(fileName, null, buffer);
                    fileinfo.IsPublic = true;
                    if (filegraph.SaveFile(fileinfo))
                    {
                        ItemLotSerialMnt oLotSerMnt = PXGraph.CreateInstance<ItemLotSerialMnt>();
                        oLotSerMnt.lotserailrecdata.Current = ser;
                        oLotSerMnt.lotserial.Current = ser;
                        PXNoteAttribute.SetFileNotes(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, fileinfo.UID.Value);
                        PXNoteAttribute.SetNote(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, "");
                        sRetVal = fileinfo.Name;
                    }

                }
                catch
                {

                }
            }
        }
    }

Accumatica支持帮助我解决了这个问题。我错过了要保存的事件

            if (filegraph.SaveFile(fileinfo))
            {
                ItemLotSerialMnt oLotSerMnt = PXGraph.CreateInstance<ItemLotSerialMnt>();
                oLotSerMnt.lotserailrecdata.Current = ser;
                oLotSerMnt.lotserial.Current = ser;
                PXNoteAttribute.SetFileNotes(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, fileinfo.UID.Value);
                PXNoteAttribute.SetNote(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, "");
                sRetVal = fileinfo.Name;
                oLotSerMnt.Persist();
            }

if（filegraph.SaveFile（fileinfo））
{
ItemLotSerialMnt-oLotSerMnt=PXGraph.CreateInstance（）；
oLotSerMnt.LOTSRAILRECDATA.Current=ser；
oLotSerMnt.lotserial.Current=ser；
PXNoteAttribute.SetFileNotes（oLotSerMnt.lotserailrecdata.Cache、oLotSerMnt.lotserailrecdata.Current、fileinfo.UID.Value）；
PXNoteAttribute.SetNote（oLotSerMnt.lotserailrecdata.Cache，oLotSerMnt.lotserailrecdata.Current，“”）；
sRetVal=fileinfo.Name；
oplotsermnt.Persist（）；
}

oLotSerMnt.Persist（）

您有INItemLotSerial DAC扩展吗？它是否包含PXNoteAttribute？请在您的问题中张贴DAC扩展。

            if (filegraph.SaveFile(fileinfo))
            {
                ItemLotSerialMnt oLotSerMnt = PXGraph.CreateInstance<ItemLotSerialMnt>();
                oLotSerMnt.lotserailrecdata.Current = ser;
                oLotSerMnt.lotserial.Current = ser;
                PXNoteAttribute.SetFileNotes(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, fileinfo.UID.Value);
                PXNoteAttribute.SetNote(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, "");
                sRetVal = fileinfo.Name;
                oLotSerMnt.Persist();
            }
