Time to look at the new INDEX function in DAX and Power BI

The INDEX function in DAX and Power BI is a powerful tool that can be used to retrieve data from tables or columns. It allows users to access specific items within a table by specifying the row number, column number, or both. This makes it easier for users to filter out certain values and analyze data quickly and efficiently.

The INDEX function also supports multiple parameters, allowing for more complex queries. Additionally, this function can return entire tables instead of just single values if needed. With its flexibility and power, the INDEX function is an invaluable asset when working with large datasets in Power BI and other analytics platforms.

The latest DAX functions in Power BI can be very "power"ful! Patrick starts by looking at the INDEX function to solve a customer problem!
