Form Settings getting cleared for system form

Question

Hi All,
I have added the code for setting editable=false for the following items in Updatemode and Ok mode.Then in add mode,i made the columns to editable = true .First time it is working fine.
the next time, I got the error message as "item is not a user defined item" on ItemCodeCol.editable = true.Then i check the form settings, the Active field for the itemcode cleared.When i set to Active as checked and run my code,it is working fine.How to solve the issue and how to avoid the setting of the fields.
This is my code :
If oSalesQuotationForm.Mode = SAPbouiCOM.BoFormMode.fm_ADD_MODE Then
                oSQItemCodeCol.Editable = True
                oSQItemNameCol.Editable = True
                oSQQtyCol.Editable = True
                oSQWhsCodeCol.Editable = True
            ElseIf oSalesQuotationForm.Mode = SAPbouiCOM.BoFormMode.fm_UPDATE_MODE Or      oSalesQuotationForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE Then
                oSQItemCodeCol.Editable = False
                oSQItemNameCol.Editable = False
                oSQQtyCol.Editable = False
                oSQWhsCodeCol.Editable = False
            End If
Thanx in advance
Regards

Hi,
This is not UDF in system form.That is , the itemcode,itemname,qty,warehouse field in the content tab of the sales quotation form.when i change the field to editable and noneditable,
1)it is allowing to set the editable property to false and true for the first time.
2) After adding the record,i navigate the record to check ,at that time,as per my code,in update mode,it is not allowing to edit.
3)When i click add menu,and i chose customer, at that time it is not allowing to add a itemcode,becoz the itemcode field is disabled.
4)when i check in form settings, in Table format, Active gets unchecked for the above fields.
5)I want to avoid this changing of active in form settings.How to to this...
