How to have accounting overhead costs applied to global procurement scenario to generate IC invoices

We have a scenario for our client where the client orders stuff from BU1 (central procurement BU) and receives at BU2. The BUs belong to different countries and hence there will be intercompany invoicing that will be generated. There are various overhead costs that need to be applied which should also show on the IC invoices while doing the transfer to BU2 hence need to be applied when doing the logical receipt at BU1. Any suggestions?
