Rank, Ignore Dimensions

[ym]

I try to rank the sales. 

My problem is that my formula does not ignore  the dimensions "Name.Supplier" and "City.Supplier"

If I select a "Name.Supplier, I get the value 0. 

Sum({<[Client] = {"=Rank(Sum(Sales))<=10"},Year={$(=GetFieldSelections(Year))},Name.Supplier=, City.Supplier=>}[Sales])

What should I change?
