Parent Child relationship between suppliers

Hello,

We have a scenario where, BPA will be raised against supplier A(Parent Supplier) and PO to be released to supplier B (a subsidiary of Supplier A) and payment be made to Supplier B.

Is this possible?

We have made the parent child relation ship by entering the "Supplier A" as a parent supplier of supplier B setup. But what is the use of it ?

As per the user guide -

"You can record the relationship between a franchise or subsidiary and its parent company by recording a value for the Parent Supplier field in the Suppliers: Organization page. Information will not automatically default from parent to subsidiary suppliers unless the subsidiary is a supplier site of the parent."
