How can i update/Remove Items from AR Invoice using SDK?

Question

Hi All,
I have 1 problem with update or remove item from sales order. here is the source code of mine.
If inv.GetByKey(DocumentNumber) = True Then
                    inv.CardCode = cardcode
                    Dim ercode As Integer
                    Dim ind As Integer = 1
                    For Each drow As DataGridViewRow In gv.Rows
                        If gv.Rows.Count = ind Then Exit For
                        ercode = drow.Cells("No").Value
                        inv.Lines.SetCurrentLine(ercode)
                        'inv.Lines.ItemCode = drow.Cells("itemcode").Value
                        'inv.Lines.ItemDescription = drow.Cells("itemname").Value
                        inv.Lines.Quantity = drow.Cells("qty").Value
                        inv.Lines.Price = drow.Cells("price").Value
                        ind = ind + 1
                    Next
                    errorcode = inv.Update
                    If errorcode <> 0 Then
                        PublicVariable.oCompany.GetLastError(errorcode, errorsms)
                    Else
                        errorcode = 0
                    End If
                Else
                    errorsms = "Not found Invoice Document Number"
End If
After update, it error "[INV1.Quantity][line:1],'Field cannot be updated (ODBC -1029)'"
Does anybody know about this?
Thanks
