New Gl Scenario FIN_CONS & EC-CS Configuration

Question

Hi All,
I am planning to implement for the first time EC-CS  in a new gl activated, no document split, 6.0 environment. I need to know whether it is mandatory (or extremely useful) to activate FIN_CONS scenario. How do I benefit from it in EC-CS?
If you have general recommendations about things to be careful in EC-CS configuration in new gl , you are most welcome.
Best Regards,

HI cetin,
please refer the below note 1070629.
below points
10. Combination of new General Ledger Accounting and consolidation (with
    a distinction between EC-CS, the R/3-based consolidation, and
    SEM-BCS, the BI-based consolidation).
Information about EC-CS: You can also carry out an online transfer from
FI (new general ledger) to EC-CS as before in the classic FI environment
if you do not use document splitting.
If document splitting is active, all of the lines from the FI document
that are in the BSEG table are transferred to EC-CS. This includes the
lines in the BSEG table that are split automatically in the new general
ledger in the same way as in the classic environment. This means that
the information added by document splitting (new line items and field
contents that are not in the BSEG table) is not transferred to EC-CS. *
Therefore, the realtime update is useful only if you do not require any
field contents in EC-CS that are filled by document splitting in the new
general ledger.
Additional information: Transaction codes for reconciling the totals
tables:
=> classic general ledger (reconciliation of the ECMCT and GLTO totals
tables): transaction CXNR
=> new general ledger (reconciliation of the ECMCT and FAGLFLEXT totals
tables): transaction CXNZ
In technical terms: In the AC interface (function module
AC_DOCUMENT_CREATE), the EC-CS component processes the field contents of
the T_ACCHD, T_ACCIT and T_ACCCR structures, but it does not process the
T_ACCIT_SPL and T_ACCCR_SPL structures.
In terms of the periodic extract and rollup (of EC-CS): Both are also
possible in the new general ledger:
=> Direct rollup from the new general ledger totals table FAGLFLEXT
=> Periodic extract (still) from totals table GLT3 (trading partner
characteristics and consolidation transaction type) and including totals
table FAGLFLEXT (the account balances in particular). Totals table GLT0
is no longer used.
However, this means: Although you may (also) save the trading partner
characteristics and consolidation transaction type in the FAGLFLEXT
totals table, you cannot deactivate the GLT3 totals table for the
preparations for consolidation if you are using the periodic extract.
Important: As before, the (new) FI segment characteristic is not
persistent in the GLT3 totals table. However, if you want to carry out
consolidation using the segment characteristic despite this, you can
only use the rollup in conjunction with user exits.
Information about SEM-BCS and Profit Center consolidation in particular:
Profit Center Consolidation is also available when the new general
ledger is active.  For more information, see Notes 852971 and 826357.
See also SAP Note 1256119.
I hope above will help you.
