Required control on Inter-company Transactions entered by the user

Hi Team,

I have a requirement from the customer following. Please guide me to fulfill / required setups for this.

Requirement Detail:

Intimation of inter-company transactions to the corresponding entity – A control to be put in place so that if an inter-company transaction is made in the Indian entity against the US entity, US entity would receive a notification of such a transaction and the corresponding entry would be passed in the US entity by the user in the same period. In this way, there is no transaction missed out in Oracle.

Note: we don't have AGIS configured in our process/system.
