So while creating new sale document type in VOV8, you can also differentiate the pricing procedure by assigning some value there.
In most of the cases, for one customer, you would be having different sale order type and for those, you have to define which pricing procedure should flow in sale order. It is based on the assignment you do in OVKK.
For e.g.
In Oil business most of the time when material is leaving from vendor premises same price is applied.
It may possible that when you booked order price was 100
During invoicing price is 105.
So SAP provided flexibility for user if needed to have different Price Procedure at sales order and billing level.
If you don't assign the document pricing procedure to the order types system will not determine the pricing procedure while creating sales order with that document type.
Pricing procedure will get determine based on this combination,
Sales area+Document pricing procedure(Order or billing)+Customer pricing procedure-->Pricing procedure.
If you want to redetermine the pricing procedure at billing you need to assigning Document Pricing Procedure to Billing type based on this new pricing procedure will determine while creating invoice.
When create sales order you need to enter document type based on this document type system will check the document price proc of that document type then it checks is there any pricing procedure determined for this document price proc if available system will execute that pricing procedure in that sales document type.
