5 Leveraging Level of Detail Calculations

Having considered row-level and aggregate calculations, it's time to turn our attention to the third of the four main types of calculations: level of detail calculations.

Level of detail calculations (sometimes referred to as LOD calcs or LOD expressions) allow you to perform aggregations at a specified level of detail, which may be different from the level of detail that is defined in the view. You can leverage this capability to perform a wide variety of analyses that would otherwise be quite difficult.

In this chapter, we'll cover the following:

  • Overview of level of detail
  • Level of detail calculation syntax and variations
  • Examples of FIXED level of detail calculations
  • Examples of INCLUDE level of detail calculations
  • Examples of EXCLUDE level of detail calculations
