New GL - ICR 002 - Intercompany reconciliation with New / Parallel Ledger

Hi Gurus,

I will realy appreciate your help on this topic.

Business need

Reconcile GL accounts (non-open item) betweed different trading partners

Proposed solution

Activate intercompany reconciliation process ICR 002

Context

We are using NEW GL with 2 parallel ledgers (1 leading 0L and one additinal ledger XY)

All my companies are in the same system (sender = receiver)

Question 1

SAP IMG documentation states that:

Define Ledger

In this Customizing activity, you can create and maintain a Special Purpose Ledger . This step is mandatory if you are configuring a system that is supposed to be used as a source system for intercompany account reconciliation

"Source system" is not the system on which the reconciliation is done. Is my understanding correct?

Question 2

if my understanding is wrong, then i'll need to activate global ledger in transaction GCVO.

When doing so, and going to transaction GCL2, i have following two ledgers available:

1. 1B FI-LC: Dir.Pstng Bus.Ar.Rollup
2. G0 Global direct posting ledger
   

Both of them are assigned to totals table GLT2 (which is not the totals table for NEW GL --> FAGLFLEXT)

Both of them are with ledger currency USD while my group currency is EUR

How should i change this configuration ?

Question 3

Why am I  not able to use leading ledger 0L ?

Question 4

Please advise if any care points should be highlighted

Thank you very much for your help
