CO Certification

Hi Guys,

I'm giving my CO certification next month. I've been preparing from the SAP course materials. I would really appreciate it if you can help me out with sample questions in Product Costing, Cost Object Controlling and Profitability Analysis. I was able to find quite a few for Cost Center Accounting and Internal Orders but not for the topics mentioned above. Any advice would also be extremely helpful!

Thanks,

Harish
