This Dev camp session will be led by Alex Power from the Power BI CAT team. Alex will teach you how to get started with creating custom functions to aid in the reusability of transformation patterns and how to add robust documentation to your Power Query queries. As this is a code first session, we’ll explore primitive and structured data types, implicit and explicit return values, the Power Query / M language VS Code extension and more. The information presented in this session will be applicable to all places where Power Query is found.

Session Prerequisites

Campers should be familiar with creating and testing queries using Power Query. Previous experience reading and writing M code in the Advanced Editor window is helpful but not required.
