Will there be Cost group created after enter org parameters for a new INV org

Hi,

We would like to know if cost group will be created automatically after entering costing details in org parameters in a new INV org?

We see that 2 cost groups are being created by default automatically under the inv org

And the one among that being assigned as default cost group in org parameters.

The problem is sub inv is created with a different cost group and now we are not able to change it.

Any inputs on this will be helpful.

Thanks.
