Download Sample Power BI Fileĭownload the sample Power BI report here: Similar to many other tabular functions, the main benefit of this function is when used to create a virtual table in a measure expression. The expression should return true or false, and can include AND/OR functions or operators. The filter function requires a table input and an expression. This function does not change the columns (unless it is used as an input of column manipulation functions such as SELECTCOLUMNS or ADDCOLUMNS). The FILTER function in DAX is a simple function to use for filtering rows of a table. The result of filtered expression is used as an input to the Calculate function to provide the sales of the filtered data. Filter function used in a DAX measure in Power BI Sales of Red OR CM =ĭimProduct='Red' || DimProduct='CM' Using a tabular function inside a measure allows us to create virtual tables dynamically based on the filter conditions in the visualizations in the table.Īs an example, I can use the below code to get the Sales of all products that their color is red OR their size unit measure is CM. Similar to many other tabular functions, the common use case scenario for them is to use them inside a measure. Using filter function inside other functions in Power BI and DAX Using Filter function in a measure As a result we have a table with one column: name of the products which their color is red and their size unit is CM. In the expression above, the result of the FILTER function (which is a virtual table) is used as an input table parameter for the SELECTCOLUMNS function. You can use other functions such as the SELECTCOLUMNS or the ADDCOLUMNS or any other table manipulation functions to do that. It will not change the number of columns or the order of it. The Filter function only reduces the rows of a table. Using filter function with multiple conditions in Power BI Filter does not change columns The output will be only products with their color as red, and their SizeUniteMeasureCode as CM. The “&” in the expression above means AND. You can separate them using AND or OR functions, or their equivalent operators (& and ||) Filter 2nd example = FILTER( Filter function with multiple conditionsįilter expression can have multiple conditions too. If you want to make it case-sensitive, you can use exact match functions as I explained here. Note that DAX is not case-sensitive, “Red” and “red” would be the same. The Color field in the DimProduct will be filtered to only include Red as below Filter function in DAX used to filter a table with one condition in Power BI If we want to have a subset of the DimProduct table for those products that their Color is Red, the expression can be as below Filter 1st example = FILTER( Here are some samples of using the Filter function as a calculated table. Samples of using Filter as a table expression This is an expression with a Boolean result (means has to return true or false)
