</BOM>
Program Code to add
            Dim oSapObject As SAPbobsCOM.Documents
            oCompany.XMLAsString = True
            oSapObject = oCompany.GetBusinessObjectFromXML(Body, 0)
            If oSapObject.Add <> 0 Then
                Throw New Exception(oCompany.GetLastErrorDescription & " [" & oCompany.GetLastErrorCode & "]")
            End If
Any help would be greatly appreciated. This is sort of urgent and needs to be done immediately.
Regards,

PS: The error is coming on oSapObject.Add - it is able to read the invoice from XML, the error comes when trying to add it. All relevant values mentioned in XML are present in the database, and I am able to add an Invoice from the UI.

I realize this might not be to much help but everytime I have ever gotten an internal error code it has always turned out to be a SQL error. For instance there could be something in transaction notification that doesnt jive with your submission or something along those lines. Perhaps you could try a more simplified invoice as a test such as just send one item with a price and no UDFs .
Sorry if that is not much help.
