Published on Aug 12,2024:
In this video, we'll explore the concepts of row-level and filter-level contexts in Power BI, which are fundamental for creating dynamic and accurate calculations using DAX.

Row-Level Context:
Row-level context refers to the context in which a formula or expression is evaluated for each individual row of a table. When you create calculated columns or measures, Power BI processes each row independently, applying the DAX formula to each row within its unique context.

Filter-Level Context:
Filter-level context, on the other hand, involves the application of filters to your data model. Filters can be applied through slicers, filter panes, or by relationships between tables. These filters impact the data that is visible and accessible to your calculations, allowing you to focus on specific subsets of your data.

Why It Matters:
Understanding these contexts is crucial for creating effective DAX formulas. By mastering row-level and filter-level contexts, you can ensure your calculations are accurate and reflect the intended insights from your data. This knowledge will enable you to leverage Power BI's full potential, making your reports more powerful and insightful.
