Error when posting AR Invoice with serial

Question

Hi experts, just want to ask what is the problem when posting AR Invoice with serial number. The error is "Internal error (-5002) occurred [الرسالة 131-183]"
Here's my code :
                            If Not oSerial Is Nothing Then
                                oSerial.DefaultView.RowFilter = "product_reference_code = '" & oDrView("product_reference_code") & "' " 'AND site_reference = '" & oDrView("site_reference") & "' "
                                For Each oDrSerial As DataRowView In oSerial.DefaultView
                                    Try
                                        .Lines.SerialNumbers.Quantity = 1
                                        .Lines.SerialNumbers.InternalSerialNumber = oDrSerial("serial_no")
                                        .Lines.SerialNumbers.Add()
                                    Catch ex As Exception
                                    End Try
                                Next
                            End If

Hi Bryan,
Have you try to debug it , which line is causing problem.
With serial numbers you don't have to set the qty.
other fields that need to be set are :
for (int count = 0 ; count < totalcount; count ++)
     if (count > 0)
          .Lines.SerialNumbers.Add();
     .Lines.SerialNumbers.SystemSerialNumber = SysSerialNum;
     .Lines.SerialNumbers.ManufacturingSerialNumber = ManufacturingNum;
     .Lines.SerialNumbers.InternalSerialNumber = internalserialnumber;
     Count++ ;
Hope it will help.
Regards
