Service Purchase Order Between Two Business Units Under the Same Legal Entity

Summary:

We have the following business requirement in Oracle Fusion Cloud:

• BU-1 and BU-2 belong to the same Legal Entity.
• BU-1 acts as the buyer/service receiver, while BU-2 provides the service.
• BU-1 must raise an actual service Purchase Order for the services provided by BU-2.
• The process should support service receipt/confirmation in BU-1, followed by an AP invoice matched to the PO.
• How to capture the Accounting impact of Expense for BU-1 and Revenue for BU-2

Could you please advise on the recommended Oracle Fusion approach for this scenario?
