Context Transition is a fundamental evaluation mechanism within DAX that operates by automatically converting row context into filter context whenever specific conditions are met. This process relies on the simultaneous presence of active iteration creating row context and an invocation of `CALCULATE`, which serves as both a function modifier and the operator triggering this theoretical transformation. The concept belongs to the domain of data analysis engine evaluation logic, functioning within parent disciplines like dimensional modeling and measure calculation optimization where it ensures measures are evaluated against precise filter states derived from row-level attributes.
