Power BI Tips and Tricks (Includes Time-Saving ChatGPT Prompts) - Deep Dive into the New DAX Functions

The video tutorial introduces three powerful DAX functions: offset, index, and window, available in Power BI from December 2022. It covers setting up data tables, creating a total sales measure, and demonstrates each function's use. The offset function allows dynamic comparison of rows, the index function compares values to a specific index, and the window function enables dynamic calculations over a specified range. The tutorial encourages viewers to explore these functions to enhance DAX development.
