Hi Prasun,
I guess you might have already received the information by now.
In case you have not.
You have mentioned 2 kinds of profiles in your question.
RZ10 is the transaction to maintain the profile parameters like changing things like default logon client, maximum runtime for dialog workprocess, etc
PFCG is the transaction for maintaining authorizations. And profiles generated in PFCG are authorization profiles where you maintain which transactions a user can access, etc.
So, you are interested in which of these profiles?
Best Regards,
Akshay
