DAX Summary Query to Table Example in Power BI
The core theoretical mechanism described is **Context Transition**, a specific rule within Data Analysis Expressions (DAX) where measures act as filter revisers that automatically generate new rows in the result set by adding current row filters to the context prior to expression evaluation. This principle governs how scalar definitions are transformed into vector results through an iterative process involving table derivation and column iteration, ensuring that aggregate functions like SUMX operate strictly within a filtered subset of derived temporary tables rather than the entire model universe.
