Vendor Price Schema

Dear SAP Guru,

In Retail Business business runs with 2 types of Trading Terms.

1) Margin Based

2) Cost based.

Margin based the Margin will calculated based on current Product's MRP and Mark down Margin. and in Cost based , Retailer fix the Price based on Mark up Margin. We can either configure in Vendor Price Schema. There are centrain Vendors who supplies some products based on Margin and some Products on Cost base for such cases Vendor cannot take both Price Schema.

I am seeking your help is there any configuration so that same can be controlled through PIR records.
