The process for posting intercompany transactions is as follows:
1. The initial entry is parked.
2. Then an email is sent to the other branch to view the document.
3. On approval of the transaction, the parked document is then posted to the g/l in both companies. The company receiving the revenue will be the one responsible to book into system using the US dollar as base currency.
