As you know already, I'm a big fan of using Set Analysis in my QlikView applications, especially for Point In Time Reporting. However, there might be some specific situations in which Set Analysis just won't cut it and you need an alternative... Continue Reading to discover it! (Demo Script included...)
Today we continue with 'The Magic of Set Analysis' Series and, in this post I will share with you a "goodie". Something that has helped me speed up the Development process on new projects, and is specially useful when creating SiB's (Seeing Is Believing) or Prototypes for prospective clients, where the time is often short.
I have always believed that Set Analysis' Raison d'être is to satisfy a basic need in any BI Tool: the ability to perform "Point In Time" Analysis.
