Inter-Company Reconciliation in ECC 6.0

Hi Guru's,

We are implementing ECC 6.0 version for 560 Company Codes and wondering do we need to configure the new Inter-Company functionality for reconciliaiton. It gives me a feeling that this functionality makes more sense if you have Company Codes in different clients/different systems etc., To my knowledge all inter-company postings within a client should get reconciled automatically.

Could someone please share some your views on this?

Thanks in advance.
