Context & Filtering
Understanding Filter Context
The invisible set of active filters driving every Power BI cell.
Syntax Definition:
Conceptual foundation
Overview
Filter Context is the cumulative set of filters applied to the semantic model by slicers, visual axes, filters pane, and cross-highlighting.
Architectural Deep Dive
In Power BI, a measure has no value in isolation. Its value is entirely determined by its Filter Context. When you look at a table visual with Country on rows and Year on columns, the cell at (Norway, 2025) has a Filter Context of Customers[Country]='Norway' AND Date[Year]=2025.
Canonical Pattern Example:
// Evaluates strictly inside active filter context: Total Revenue = SUM(Sales[Revenue])
Common Anti-Patterns & Mistakes to Avoid
- •Confusing Filter Context with Row Context.
- •Not understanding that CALCULATE is the only mechanism to overwrite or remove Filter Context.
