OPM multiple cost type simulation

Hi Experts,

In OPM Financial guide, it mentioned that:

The Fiscal Policy options define the Legal Entity-wide parameters that determine the

cost type that will be used for inventory valuation, the default material and overhead

cost components and analysis codes for actual cost processing, additional cost types

used for costing simulations.

So in OPM system, we set cost type as PMAC in primary ledger, for simulation purpose, in fiscal policy we assigned another cost type through valuation method for second ledger. Can anybody share a scenario with detailed steps on how to do the simulation to verify the result?

Regards
