Customer Material Info Rec-Partner function

Folks,

We would be using the Customer Hierarchy standard functionality found in transaction VDH1N, partner function type 1A, and customer account group 0012. We would also like to use this hierarchy to drive "Customer-Material Info Records".

To my knowledge, when creating a standard sales order, SAP functionality uses the sold-to party (SP) to retrieve the Customer-Material Info Records and does not consider at hierarchy partner function 1A.

Can you please advise me if this can be changed, through standard configuration settings, to have the sales order retrieve cust-material info records for partner function 1A as well as the sold-to party SP?

Thanks
