Update too slow of a user field..

Question

Hello everyone,
I have a problem with the update of a massive field in user stores.
The update works but it takes too much time, about 1.5 seconds to Article!
This is my code sample:
            Dim sql As String = ""
            sql = "SELECT T0.ItemCode,T1.OnHand FROM OITM T0,OITW T1" & ControlChars.CrLf
            sql = sql & " WHERE T0.ItemCode=T1.ItemCode  " & ControlChars.CrLf
            sql = sql & "  AND T1.WhsCode='{0}' " & ControlChars.CrLf
            sql = sql & "  AND T0.FrozenFor='N' AND T1.OnHand>0"
            sql = String.Format(sql, WhsCode)
            Dim line As Integer = -99
            Dim ret As Boolean = False
            Dim itm As SAPbobsCOM.Items
            itm = CType(_SboCy.GetBusinessObject(BoObjectTypes.oItems), Items)
            Dim rows As DataRowCollection = GetRows(sql)
            For Each R As DataRow In rows
                If itm.GetByKey(R("ItemCode").ToString) Then
                    If line = -99 Then
                        For i As Integer = 0 To itm.WhsInfo.Count - 1
                            itm.WhsInfo.SetCurrentLine(i)
                            If itm.WhsInfo.WarehouseCode = WhsCode Then
                                line = i
                                Exit For
                            End If
                        Next
                    End If
                    itm.WhsInfo.SetCurrentLine(line)
                    itm.WhsInfo.UserFields.Fields.Item("U_MyQty").Value = CDbl(R("OnHand"))
                    ret = (itm.Update = 0)
                End If
            Next
            NothingObj(CType(itm, Object))
Please know me suggest another solution?
Thanks

Hi Enrico,
If you perform the same update using the SBO client (ie go to the Stock tab in Item Master Data and set a value in your UDF field) is the speed faster than the DI API? Do you have any customisations in the SP_SBO_TransactionNotification proc in the database? If you update a standard system field rather than your UDF field is the speed in the DI API the same?
Kind Regards,
