I have a problem to add data with UDO.

Question

this is my code:
  Try
            Dim oCompService As SAPbobsCOM.CompanyService
           oCompService = ap.oCompany.GetCompanyService()
           ap.oCompany.StartTransaction()
            Dim oDocGeneralService As SAPbobsCOM.GeneralService
            Dim oDocGeneralData As SAPbobsCOM.GeneralData
            ''in this line is the Error. ***
            +*oDocGeneralService = oCompService.GetGeneralService("MyDocUDO")*+       
  Catch ex As Exception
            If (ap.oCompany.InTransaction) Then
                ap.oCompany.EndTransaction(SAPbobsCOM.BoWfTransOpt.wf_RollBack)
            End If
   End Try
in this line trought a exception that it said: "Interface not registered". I think the problem is the object oCompService but I don't know solved. Anyone Can Help me??
Thanks.

Answer 1

...you are sure you have created the UDO "MyDocUDO" ? that error appears in the case that there is any UDO with that name, to verify if this UDO exists go in Business One to Menu Tools --> Customisation tools --> Objects registration wizard, in the wizard click next -> update existing object -> next : you will see the list of existing UDO....
I have verified that the object exists, even I have verified it in the table OUDO. I think that the error owes to the DLL SAPBOSCOM, but i don,t know solved it.
Thanks.
