Should you use DAX user-defined functions (UDF) or calculation groups? Learn when to use either, and how they complement each other in the design of a semantic model in Power BI.

This article describes the different roles of user-defined functions and calculation groups, explaining when to use either, and how they complement each other in the design of a semantic model.

The introduction of user-defined functions (UDFs) in DAX changes the way we think about code reuse. Before UDFs existed, calculation groups were the only mechanism for shar...

Create a DAX model-independent user-defined function (UDF) to easily apply the like-for-like pattern to your data.

This article offers a comprehensive guide to changing the like-for-like pattern into model-independent functions to enhance flexibility and simplify DAX code.

DAX user-defined functions (UDFs) are a powerful tool for improving the quality of your semantic models. DAX authors with an IT background are accustomed to creating generic code using functions. However, ma...
