Planning & real time integration with FI

Dear All,

We are doing Cost center planning. We have activated new GL functionality in FI. This has one advantage i.e. real time integration with CO=FI .

My question is how this planning data which is in CO will flow to FI if I have not activated GL planning (Special purpose ledger / new GL) in FI .

Or will that be always reconciliation between them.

What I belive is

Planning data will flow from primary cost element (to which we are doing planning with cost center) to respective GL account & for this we have to activate GL planning & maintain the planning version in FI. Is this correct ?

Regards,

Abhijit
