Pricing of configurable material

Hi experts,

I want some help for following scenario.

Suppose I have one Configurable material as "A".

For which I require 10 multilevel items for manufacturing.

Each 10 multilevel items have 20 characteristics.

If I want to calculate price of my finish product "A"

by using different combination of multilevels and characteristics how would I maintain it in SAP.

I know I have to create Configurable material.

Some SuperBOM and maintain classification for this materil.

But where I get Price for these permitations and combinations for "A".

What are the configurations?

If any one have any document related to this scenario please mail me on ravi3981@gmail.com

regards,

rb.
