How are non-cost center Controlling objects best modeled in PCM?

Question

I appreciate that ALG developed Profitability and Cost Management, and they apparently were unaware of
or did not consider that SAP ERP uses more than a single controlling object of a cost center; specifically
internal order, WBS element, real estate object, etc.
My question is how are these other controlling objects best treated in PCM?
For example,
I have a planned trade show internal order to showcase my companies products
in Berlin to European retailers.  I have planned travel costs, display costs,
space rental costs on this internal order.
Normally, I would settle this internal order to CO-PA to determine the planned
profitability of my Europen retail customers.  Unless I make this order a faux cost center,
I don't see how to model it in PCM.
If I exclude this order, then the profitability resulting in PCM is suspect --
leaving out a major chunk of customer specific marketing expense.
Or is the process to settle the planned internal order cost to CO-PA, but
transfer the planned costs from PCM back into CO-PA, which would have the
benefit of being mutually exclusive and collectively exhaustive.
Jeff Holdeman hinted at the restrictions imposed by planning in ECC.  Yet
without a more comprehensive approach, I am concerned that PCM still
does not represent a complete profitability planning solution.

Hi Deepak.
You can verify is the cost center was posted on document running tcode SE16N on the FALGFLEXA table, put the document number to do research.
After you can trying to post the new document through Tcode FB50L choosing or not a legder specific, then verify the document was posted correctly running the Tcodes SKb1 or Se16N with FAGLFLEXA table again.
Also you can check this link Checking the Allocation of General Ledgers to Cost Centres
