COPA Planning Framework

Dear Experts,

I am doing COPA Planning Framework.

First Step: Created Planning Level as Co.Code Sales Plan.

Second Step: Created Planning Package as Co.Code Sales Plan for 2010.

Now I am trying to create Planning method. But system automatically showing that Planning Level as Planning Method.

Why it is like that?

Then Should I need to create directly the Parameter Set?

Pls correct me.....
