Column calculation that returns value in a hierarchy

I have a company ownership hierarchy table, where I need to add a column that indicates the ultimate parent. See example:

 

 

 

I need to calculate ultimate parent column based on the parent company ownership of company a. I have about 100k child companies with unique ids, each of which are associated with various parents with varying levels of ownership. 

The idea is to calculate a column that returns the ultimate parent based on the maximum percent ownership of each indiviual child company.

 

I've looked around the forum and tried a few things with no luck...

Thanks!

    For the example given, I would think that the formula would go something along the lines of:

     

     

    Column = 
    VAR __tmpTable = FILTER(ALL(Table),[child company] = EARLIER([child company])
    VAR __max% = MAXX(__tmpTable,[% ownership by parent])
    RETURN 
    MAXX(FILTER(__tmpTable,[% ownership by parent] = __max%),[parent company])

     

    Something like that.
