Click here to watch his 50-minute video, containing 8 detailed demos, in which Marco teaches you about row and filter contexts, as well as the many ways to manipulate it, so that you can express yourself fully in DAX. Amongst others, Marco explains how to use DAX functions that help you work with context, including those that propagate it across table relationships. FILTER, ALL, EARLIER, VALUES, RELATED, and RELATEDTABLE functions are covered in Marco’s explanations, demos, and a 1000-word article that accompanies the video.
