Explanation ALLSELECTED is one of the most complex functions in DAX. When used improperly it can lead to unexpected results. As a rule of thumb, you should not use it in iterative functions. It is preferable to use it only as a CALCULATE filter remover, not as a table function.

What is Lineage? Lineage is a part of DAX mechanics that enables us to use tables as filter arguments for the CALCULATE function. It’s also used in row2filter context transition and other aspects of the data model that involve filter propagation throughout the model. We can state that lineage is

Crossfilter is a feature of DAX when it filters the underlying dataset even though there aren’t any visual filters present. Introduction In this example, we will explain a very important feature of CALCULATE filter arguments. We will also explain why you should always prefer the combination of ALL/REMOVEFILTER + VALUES

When using whole tables as filter arguments to CALCULATE, you are using an expanded version of the model, which consists of the table used in the arguments, as well as all other tables in the data model that are linked to that table through a 1-* relationship. We will explain
