DAX UDFs let you define reusable, typed functions that can be invoked from measures and calculated columns, reducing boilerplate and ensuring consistent patterns across your Power BI models.
Create a simple DAX UDF named 'CircleArea' that computes the area of a circle from a numeric radius.

Reusable DAX functions are created using UDF definitions with a createOrReplace wrapper, enforcing type safety and reducing boilerplate across Power BI semantic models. You define typed functions with explicit parameter subtypes and modes like Val or Expr for deterministic updates.
DAX UDF parameter modes include Val and Expr, along with AnyRef references for flexible function inputs. These modes define how arguments are evaluated and passed within semantic models, ensuring type-safe function definitions for measures and calculated columns.
Yes, DAX UDFs support reusability across measures, time-intelligence patterns, and complex calculations within semantic models. They accommodate scalar, table, or reference returns to handle varied analytical use cases consistently.
The best way to enforce type safety in DAX measures is using UDF definitions with explicit parameter subtypes and modes. This approach centralizes logic with a createOrReplace wrapper, ensuring consistent, typed patterns across your semantic model.
No, the dax-udf Skill has no external dependencies. It deploys DAX UDFs with a createOrReplace wrapper directly into semantic models, and optionally supports directories for scripts, references, and assets to organize your codebase.
