This video (0:00) provides a high-level introduction to DAX Contexts in Power BI, emphasizing that understanding context is the most crucial concept for a Power BI developer (0:05).
Context determines the specific set of data used for calculations, enabling dynamic, data-driven results (0:10).
Here are the key concepts covered:
Filter Context (0:50): This is the invisible set of filters applied by Power BI before a measure is evaluated, determining which rows are visible (0:57).
Sources include slicers, visual axes/legends, report filters, and the CALCULATE function (1:08).
Row Context (2:27):
This context exists when DAX iterates through a table row-by-row, such as in calculated columns or iterator functions (e.g., SUMX) (2:31).
Note that standard measures do not have a row context (2:51).
Context Transition (3:08): This occurs when CALCULATE is called inside a row context, automatically converting that specific row into a filter (3:09).
