Demystifying Power BI Variables: A Comprehensive Guide to Understanding DAX and M Variables
Вставка
- Опубліковано 21 сер 2024
- This session is a deep dive into the use of variables within DAX and Power Query M for developing complex logic in Power BI solutions. It begins with an exploration of the Queries pane as the base for variable creation in M, using the "let" and "in" operators, then examines the use of both global and local variables in DAX, emphasizing their nature as constants. Common use cases and potential pitfalls will be discussed, along with the concept of precedence in variable usage across multiple scopes. Attendees will gain a nuanced understanding of variable application in the two main engines of Power BI.
