Period close in AX 2009 without affecting other companies


AX 2009 - In multiple companies (entities) implemetation situation, how can one company’s period in GL be closed without impacting other companies.

EX - Holding company A

Sister companies - B, C & D

If I close the period for company B, that is closing all the rest of companies, which is not what I want system to do.

The way I closed the period was GL > Setup > Periods > Close for compay B in this example and I found at other companies (C, D & A) period got closed as well. May be I am not closing correctly here.

Can this be achieved in AX? If so, how? What is the correct way of closing the book in AX?

Your help is greatly appreciated?
