Generate Invoice for Intercompany Invoice split per country or per Employee based on BU

Summary:

Our business team is currently having trouble computing taxes on intercompany invoices for timecard labor transactions. To make tax calculations easier per country, the business wants to separate or split the labor invoices on the intercompany invoice by country.

Currently, our setup uses a single global intercompany contract that consolidates labor transactions across provider and receiver countries into one combined intercompany invoice. We would like to know if it is possible in Oracle to automatically split these intercompany invoices by country, or if there are any articles or guides available on this setup.

While we are currently looking into Inter-Project Billing as a option, we would prefer to find a way to achieve this invoice separation without completely abandoning or significantly disrupting our current process.
