Ram ,
Please read Amber's reply again, i feel it have all the information you need.
..From VC perspectives , for it is the FM CEI0_GET_CONDITION that can be used.
values you already have just match with conditions and you will have price maintained in condition record.
Please take a help from some one who work on SAP SD and he/she will explain you how it works.
Also if you dont have sales area setup , how yoy are planning to carry out sales activity?
If you expect a solution from forum , its a suggestion please explain your issue correctly.
Thanks
Ritesh
