misc charges in sales order

Hi all,

as we know that auto charges are applied for the customer, item , delivery mode and i have added 2 new fields in the same form

when we create a new sales order the charges code will be applied based on the settings (customer , item , delivery mode) this is standard on the auto charges, as i have added one more filter selling model , I want filter to pick the selling model which is there in sales line field of the sale order.

We need to write the code in some class

Any idea which class it may be??
