Consolitation Relationship Properties

Hi,

I want the hierarchy illustrated below. Entity B owns 90% of entity C, and in the consolidation of entity B we calculate minority interests of 10%. At this step, I have no doubts.

However, entity A owns entity B 100% and also owns entity C 100% (90% indirect + 10% direct). So, in the consolidation of entity A, we need to eliminate the calculation of minority interests done previously in the consolidation of entity B.
I don't know how to set the properties to do this. Can someone help me?
