In the previous chapter, we learnt what Sets are and how to create and use them. We saw an example of Top 5 customers by Sales. When we use this set, we can either use it as IN/OUT, which is a Boolean output, and which when used in our view, will give us two In and Out headers, or we can use it as Show Members in Set, which will only give us the names of our top five customers and filter the rest of the customers.
