to give price as per sales orders

Hi Experts!

   I got a scnario where we have to give price(pr00) as per sales orders.....

Eg: sales orders            Price

       01-99                    500

       100-199                1000

       200-299                1500

       300 +                    2000

Here the system should pick up the price as per the sales order.....like for sales orders 01-99 it should propose price as 500  and from sales orders 100-199 it should propose price 1000....like that...

Is this possible in standard sap or not...

Pls do the needful..

Regards

Bala.
