Rank function : you can create a calculated field using Rank function. Rank(expression,[‘asc’],[‘desc’]) For  example of rank function we take below table Example:  Stores Sales A 10 B 20 c 20 d 40 e 50 a.        If we use ‘ Rank(Sum([Sales])) ’ we get the result as Stores Rank Function Sales A 5 10 B 3 20 c 3 20 d 2 40 e 1 50 Here rank 4 is skipped. b.       Rank_Dense () RANK_DENSE(sum([sales])) Stores Rank Function Rank Dense function Sales A 5 4 10 B 3 3 20 c 3 3 20 d 2 2 40 e 1 1 50 On this same number gives the same rank. on above example on two cells sales amount is 20 . then it gives same rank to both. c.        Rank_modified() Create a calculated field using rank_modified function  Rank_modified(expression,[‘asc’I...
