Empty Values vs. Zero,In this chapter, we will look at a very specific DAX behavior, and that is how DAX treats empty, missing, and null values.

The CALCULATETABLE Function,Now that you are officially a DAX expert, you are ready to confront DAX expressions that will truly test your knowledge and understanding of DAX. One of the DAX functions that can only be understood with a clear grasp of how DAX works is CALCULATETABLE, and this rather obscure function is the last function we will investigate in this book.

Evaluation Context,xpression differ. At this stage, you understand that calculated columns are row-level calculations and that measures are calculations that are performed at the report level. However, we need to be more specific regarding this differentiation, and you need to understand that the definitive difference

Iterators, of a DAX expression. Any DAX function that ends in an “X” is an iterator, such as the “X” aggregators: SUMX, AVERAGEX, MAXX, MINX, COUNTAX. There are also “X” iterating functions that aren’t aggregators such as CONCATENATEX and RANKX. Just to make life even more confusing, there are iterating funct
