Thank you very much .
It will work but I was looking for simpler solution like in "Northwind"  where price is kept in table Products but if there is new price in table OrderDetails both(old and new) are being kept. I hope my comment made some sense to you
Please see the second paragraph in my comment http:#a39171150.  What I discussed there is the same thing as you cite from the Northwind sample database.

Thank you. I will try to "break down" the details form Nortwind sample database in order to try to figure it out.
