I have a table called CarSales with the following sample data:

I already have a measure that ranks all Brands by sales:
Rank = RANKX(ALL('CarSales'[Brand]),[NetSales])
However, I need another measure/column **"Rank(Country)" ** which ranks the Brands within the Country group (without having to display the Country group in the table)
Thanks

Try the following measure:
= VAR ThisCountry = MIN( CarSales[Country] ) RETURN RANKX( FILTER( ALLSELECTED( CarSales ), 'CarSales'[Country] = ThisCountry ), [NetSales] )
