Using alternate states with Set Analysis


The alternate states function was introduced to QlikView in version 11. It allows us to create a named set of selections separate to the default current selections. At a simple level, this allows us to create a side-by-side analysis to allow us to easily and quickly compare one set of selections versus another. At a more complex level, it opens up a wide range of analysis possibilities.

In this recipe, we will create two states and look at how we access those states in the Set Analysis syntax.
