This course focuses on using DAX (Data Analysis eXpressions) to create advanced Power Pivot data model calculations. We will review what you learned in "Power BI - Go Beyond PivotTables with Power Pivot" and take your calculations to the next level using advanced DAX formulas. You will learn over 20 DAX functions that allow you to perform calculations that were not possible with standard Excel. We will also review the use of a date or calendar table that will enable us to perform date analysis that was never possible before. This will allow us to use the new time-intelligent functions to perform complex calculations on our data like month-to-date, quarter-to-date, year-to-date, last year, same period, last year-to-date, etc. You will also learn the DAX calculation process to proof and validate your calculations. We will be using Power Pivot to create our DAX calculations. However, the process is very similar in Power BI Desktop and the functions and formulas are identical. If you are using Power BI Desktop, you should be able to follow along and learn how to create advanced calculations. This session is presented using Excel 2019/Office 365. Regardless of the version, you are using, most concepts covered in this course apply to all versions of Excel.
