.net connector 3 - Invalid Delta Manager object ID (2 <=> 1)

[Former Member]

Hi,

Here is my sample .net code;

Dim f As IRfcFunction = Nothing
        Dim structImport As IRfcStructure = Nothing
        Dim tblImport As IRfcTable = Nothing
        Try
           'PROD
            Dim destination As RfcDestination = GetRfcDestination("SAP", "SAT", "111111111", "111", "TR", "111.11.1.111", "0", "20", "10")
            f = destination.Repository.CreateFunction("ZFI_SEND_EXPENSE_FROM_WEB_IN")
            Dim rowcount As Integer = dt.Rows.Count
            Dim i As Integer
            For i = 0 To rowcount - 1
                structImport = destination.Repository.GetStructureMetadata("ZFI_MASRAF_IN").CreateStructure()
                structImport.SetValue("FORMNO", dt.Rows(i).Item("SAPFormID"))
                structImport.SetValue("BUZEI", i + 1)
                structImport.SetValue("LIFNR", "00" + dt.Rows(i).Item("employeeNumber"))
                structImport.SetValue("FORMTAR", DateTime.Parse(dt.Rows(i).Item("CreationDate")))
                structImport.SetValue("BLDAT", DateTime.Parse(dt.Rows(i).Item("BelgeTarihi")))
                structImport.SetValue("XBLNR", dt.Rows(i).Item("BelgeNo"))
                structImport.SetValue("DMBTR", dt.Rows(i).Item("MasrafTutar"))
                structImport.SetValue("WAERS", dt.Rows(i).Item("ParaBirimi"))
                structImport.SetValue("KDVGOS", dt.Rows(i).Item("KDV"))
                structImport.SetValue("KOSTL", dt.Rows(i).Item("MasrafYeri"))
                structImport.SetValue("SAKNR", dt.Rows(i).Item("MasrafTipiNo"))
                structImport.SetValue("MTIPI", dt.Rows(i).Item("MasrafTipi"))
                structImport.SetValue("FLAG", "0")
                structImport.SetValue("MTANIM", dt.Rows(i).Item("Aciklama"))
                structImport.SetValue("SIRKET", dt.Rows(i).Item("Sirket"))
                structImport.SetValue("ACIKLAMA", dt.Rows(i).Item("Aciklama"))
                structImport.SetValue("YURTICI", dt.Rows(i).Item("YurtIci"))
                tblImport = f.GetTable("T_EXPENSE")
                tblImport.Append(structImport)
            Next
            f.Invoke(destination)
        Catch ex As Exception
            returnm = ex.Message
        Finally

And when I run this code above, it gives Invalid Delta Manager object ID (2 <=> 1) error but still writes into SAP. How can I fix this? I mean what is this error message?

Best Regards.

Patch 3.0.11 should now fix this problem. See SAP note 1794081.

Hi Ulrich,

This is a very good news. How can I get the patch for x64 .NET 4.0?

Thank you.

Hi Cenk,

simply go https://service.sap.com/connectors -> SAP Connector for Microsoft .NET. In the download section you'll find the latest patch level.

Best regards,

Markus

Apparently that message is returned when an RFC call receives two tables with the same name. 

Perhaps it would help if you would move the statement -- tblImport = f.GetTable("T_EXPENSE")  -- outside/before the FOR NEXT loop.

Hi Case Ahr,

Thank you for your reply. I will try and let you know.

Best Regards.

In fact, you can simplify the code even more: delete the line

structImport = destination.Repository.GetStructureMetadata("ZFI_MASRAF_IN").CreateStructure()

Instead you can do something like

tblImport = f.GetTable("T_EXPENSE")

tblImport.Append(rowcount)

For i = 0 To rowcount - 1

     tblImport.CurrentIndex = i

     tblImport.SetValue("FORMNO", dt.Rows(i).Item("SAPFormID"))

     ....

     tblImport.SetValue("YURTICI", dt.Rows(i).Item("YurtIci"))

Next

However, I'm afraid this will probably not fix the problem. We are currently investigating exactly this error, which appears in a few other customer cases, but we cannot yet reproduce it locally at SAP. If the error still appears in your scenario with the simplified code, would you be willing to try out a few NCo patches for us and test whether they fix the problem? (At the moment we think it's a problem in the interaction of the NCo Delta-Manager layer and the R/3 kernel, which happens only in certain special cases.)

Thanks and best Regards, Ulrich Schmidt

Hi Ulrich,

Thanks for your reply. I feel better now when I heard I am not the only one experiencing this problem. Actually this problem occurs on the production SAP not on development. I also could not test what Case Ahrsuggested. I will also try your way and let you know.

Best Regards.

Hi Ulrich,

How can I get the patches?

Best Regards.

[Ulrich_Schmidt]

Hi Cenk,

the next patch day for NCo is still a while away. But I can trigger a beta patch, so you can test whether the fix works in your scenario.

What NCo variant do you need (x86/x64, .NET 2.0/4.0) ?

Hi Ulrich,

I want x64,.net 4.0 please. But using a beta patch on production will be dangerous

Hi Ulrich,

Can I get .NET 4.0 please?

Thank you.
