Busineaa Area

Dear Expert.

I have a little confusion about Business Area.

we have existing one Company Code e.g 1000 & ten Business Area e.g Kolkata, Mumbai, Hyderabad, Bangalore .............

now we are Rollout for a new Company Code for 2000, Like Company Code 1000 we have same Business Unit for 2000 Company Code also e.g Kolkata, Mumbai, Hyderabad, Bangalore ...........

So we have to  create again Business Area for Company Code 2000 or not. (Business Unit location is same for both Company Code)
