2023年11月的Power BI中更新了一个重要的功能,即DAX查询视图,这是一个非常重要的更新,可以在Power BI中使用DAX表达式编写查询,以获取数据模型中的各种数据,这些在未更新该功能之前都是使用外部工具DAX Stuido来完成。而2023年12月的更新,让DAX查询功能更加强大了。由此来看,Power BI的DAX查询功能正走在替代DAX Stud...
The definition of the measure that you create is saved with its source data table. It appears in the PowerPivot Field List and is available to all users of the workbook. For more information, seePowerPivot Measures. ↑Back to top See Also ...
FormulaDefinition = TODAY()Inserts today's date in every row of a calculated column. = 3Inserts the value 3 in every row of a calculated column. = [Column1] + [Column2]Adds the values in the same row of [Column1] and [Column2] and puts the results in the calculated column of the...

The same definition can be rewritten with fully qualified column references. DAX Profit = Orders[Sales] - Orders[Cost] Sometimes, however, you'll be required to use fully qualified column references when Power BI detects ambiguity. When entering a formula, a red squiggly and error message will...
For example, consider this measures’ definition. 1 2 3 Revenues := SUMX ( Sales, Sales[Sales Line Amount] ) Costs := SUMX ( Sales, Sales[Sales Line Cost] ) Profit := [Revenues] - [Costs] Copy Conventions#1 In this case, the calculation of Profit requires a single storage engine ...
This formula is inefficient, as it requires Power BI to evaluate the same expression twice. The measure definition can be made more efficient by using a variable, VAR.The following measure definition represents an improvement. It uses an expression to assign the "same period last year" result ...
Any filter expression in a CALCULATE statement overrides the existing selection of the PivotTable for the columns it contains. In the previous rule we highlighted the “reference” definition, because the FILTER that is internally used in place of the Boolean expression uses a FILTER expression that...
Create your own unique time view that differs from a regular calendar (for example, a 4/4/5 calendar) or your own definition of a financial year. Create notions such as a Power BI Calendar Table for time intelligence. These can be used to let a user pick a time horizon from a slicer...
