No-Yes-No Litware from New York will be displayed at the top of the result (N) Sorting prioritizes Location in descending order, so rows from locations like "Washington DC" or "San Francisco" will appear before "New York." Thus, Litware from New York will not be at the top. Fabrikam in Seattle will have value = 2 in the Rank column (Y) Within the "Seattle" location, Fabrikam and Litware both have UnitsSold = 100. These rows are tied, and row_rank_dense assigns both a rank of 2 because dense ranking skips no numbers. Litware in San Francisco will have the same value in the Rank column as Litware in New York (N) The row_rank_dense function assigns ranks independently for each Location. "Litware" in San Francisco and "Litware" in New York belong to different partitions and will have different ranks.
