How to distinguish invoices for global procurement PO

Summary:

We are using Global Procurement in Fusion now. Here is the case: Requisitioning BU A and Procurement BU B to purchase from external supplier, goods are shipped directly to A. And intercompany invoicing will be generated based on Financial Orchestration.

The question is: when creating supplier invoices in BU B for external suppliers, is there any fields in SLA can be used to distinguish whether the PO is for global procurement or standard procurement?
