1. Introduction
Rank Transformation:The Rank transformation allows us to select only the top or bottom rank of data. It allows us to select a group of top or bottom values, not just one value. As given in the below example, the business likes to see the Top 6 Profits based on Order date
Rank Transformation
Customer ID 1 1 1 1 1 1 Item No 150 150 150 150 150 150 Order date Jan-12 Feb-12 Mar-12 Apr-12 May-12 Jun-12 Unit Sales 11 3 2 1 1 2 Profit 11.52 3.9 2.48 1.37 1.33 2.87 Rank 1 2 3 4 5 6 Customer ID 1 1 1 1 1 1
