Why Your DAX Filter Fails: Master the IN Operator in Power BI

Through this video, we will learn another DAX called IN The IN operator in DAX tests whether a scalar value matches any value in a list or single-column table. It functions as a cleaner, shorthand alternative to chaining multiple || (OR) conditions. Syntax & Mechanics Code snippet Scalar Expression IN { Value1, Value2, Value3, ... } Constructor: Curly brackets { ... } define a single-column table of literal values. Logic: Returns TRUE if the scalar expression equals any element in the list. Negative Check: To perform a "NOT IN" check, prefix the condition with NOT: Code snippet NOT ( Sales[Region] IN { "North", "South" } ) DAX used in this video North and south sales = CALCULATE( SUM(power_bi_dax_sales_dataset[SalesAmount]), power_bi_dax_sales_dataset[Region] IN { "North", "South" } )
