# Nested top N + others

In business scenarios, it is very common for decision-makers to examine the following: Customers contributing to the most revenue, Spend Categories that consume most of the budget, Key vendors from whom we procure the most and more. 

This can be easily achieved using the top/bottom N + others feature in Inforiver. You can also 

(a) Create nested rules - like the bottom 3 sub-categories in each of the top 2 categories 

(b) Create multi-level nested rules - by increasing the number of hierarchy levels even beyond two

(c) Append the category name to 'Others' for each instance of others
