The Insert Function dialog box is the easiest way to find a DAX function that is relevant to your DAX formula. You have added a column for Unit Price at which those units are sold with the above formula. As already discussed in the chapter – DAX Syntax, it is a recommended practice to use the table name along with the column name in every reference to any column name. Usage of this handy IntelliSense feature is highly recommended. With a Power BI account, you can access a broad range of features, services, and capabilities that… When working with data, bookmarks offer a streamlined and personalized way to navigate through large…

The same formula can behave differently depending on whether the formula is used in a calculated column or a calculated field. DAX provides the IntelliSense feature that will enable you to write DAX formulas promptly and correctly. With this feature, you need not type the table, column, and function names completely, but select the relevant names from the dropdown list while writing a DAX formula. Now that you’ve learned about the Syntax of DAX formulas, let’s discuss the DAX functions and their types. This lesson will teach us to employ DAX formulas in measures and calculating columns. It is assumed that you are already aware of the basics of Measures and Calculated columns and how to use Power BI Desktop to import data and add fields to a report.
