Pricing for billing types

Hi,

I have a billing type A. And is there any place in config where i can assign the sales docuemnt pricing procedure to billing type?

As in, my issue is, i have created an order, and it has picked up pricing procedure X. But the invoice created for the same SO has picked up pricing procedure Y.

I am not sure if this should be maintained seperaytly?

Please clarify.

thanks in advance.
