Changes in OBBH - Substitution

Hi,

We want some changes in current process i.e. Business Area = Profit Center as defined in OBBH.

Now we have process a new Business Area with 3 Plants and wants Profitability as per Plant i.e.

Plant 1 = Profit Center 1

Plant 2 = Profit Center 2

Plant 3 = Profit Center 3

Can we define this process in Tcode OBBH as above.

Please guide.
