Rankx not working in a table with multiple fields

Anonymous , Measure Rank is context-specific

Like this my city Rank

City Rank = RANKX(all(Geography[City]),[Sales])

In case add city Id, which keys for the city in visual. I will still get 1 . Because now city is getting ranked inside city id

Now this will allow me to handle above

City and ID Rank = RANKX(all(Geography[City],Geography[City Id]),[Sales])

As both city and City Id are the same levels I can also use the one below
Geography Rank = RANKX(all(Geography),[Sales])

Hope this will help
