Difference Between Measure and Calculated Table in Power BI
Aspect Measure Calculated Table Definition A measure is a DAX formula used to perform dynamic, context-based calculations (e.g., sums, averages) within a Power BI report. A calculated table is a table created using DAX that stores intermediate or transformed data directly in the data model. Usage Context Used for aggregations and calculations in report visuals based on filters or user selections. Used for creating new datasets, such as role-playing dimensions, custom relationships, or pre-defined groups of data. Storage Measures do not store data ; they calculate results dynamically at runtime. Calculated tables store their data in the Power BI model. Performance Lightweight; calculated at runtime but can impact performance in large or complex data models. Can increase the size of the data model, affecting overall performance and resource usage. Creation Process Created as DAX expressions in the Fields pane , often within the same table. Creat...
