In Data Analysis Expressions (DAX) within the Power BI domain, execution logic is governed by a strict evaluation order where Filter Context establishes implicit or explicit filtering conditions on data tables prior to Row Context processing individual records for calculations without aggregation. This hierarchical mechanism dictates that filter propagation occurs first from slicers and visuals, followed by row-by-row iterative calculation functions such as SUMX which operate within the current row's scope while inheriting any active filters unless explicitly overridden. The concept forms a fundamental theoretical boundary condition in multidimensional database modeling, defining how context transitions manage the relationship between aggregate measures evaluated over filtered subsets and scalar values computed at the granular data point level.
