    Hi GhostTIT ,

    Your DAX is available, but it's for use inside a measure not column:



    The article describes the difference between column and measure, you could refer to: The differences between new measure and new column in Power BI - The Data School Down Under

    New columns are static and calculated based on existing data, while measures are dynamic and based on aggregated data.

     

    What's more, you could create the new column or measure under this tab:


    And in case you want to create a column to achieve the output, please follow the method below:

     

     

     

    ProductTop3andOthers_column = 
    VAR _a = financials[Sale_column]
    VAR _b = RANKX(financials, [Sale_column], , DESC, Dense)
    RETURN
    IF(_b <= 3 , financials[Product] , "Other")

     

     

     

    Best Regards,

    Xianda Tang
