Reconciliation Ledger: New GL
We are on ECC 6.0. While doing the overhead cost calculation for a production order, system is giving an error that reconciliation ledger substitution is not activiate and no settlement GL found for few secondary cost elemenet. In the error, system is taking to T Code OK17. My understanding is that if new GL is active, there is a real time integration between CO & FI. Any data, which flows from CO is posted to primary cost element in FI. However, when we do an overhead cost calculation, system will credit the cost center and debit the production order. In such a case, it should not generate any FI posting. Why, is the error happening and system asking for configuration in OK17, when real time integration is active in system?

With real time integration you need to define mirror FI posting accounts even for secondary cost elements in CO. Due to this FI and CO would always be reconciled. The substitution needs to be defined so as to e.g repalce first digit of cost element with a particular digit for FI account.
These FI accounts can be grouped in offsetting balance accounts which do not appear in balance sheet.
So in your case even for overhead cost calculation the mirror FI account substitution needs to be defined.
