    Hi,

    This calculated column formula works

    Column = if(SUBSTITUTE(SUBSTITUTE(Data[Category],"-",BLANK()),LEFT(Data[Category],SEARCH("-",Data[Category],,20)-1),BLANK())="",LEFT(Data[Category],SEARCH("-",Data[Category],,20)-1),"Mix")

    Hope this helps.

To handle the task in Power BI where you need to check if all values in a 'Category' column are the same or mixed, you can use a DAX formula to create a calculated column. Here’s a simplified approach:

 

Result =
VAR SplitValues = PATHITEMS(SUBSTITUTE([Category], "-", "|"), "|")
VAR UniqueValues = DISTINCT(SplitValues)
RETURN
IF(COUNTROWS(UniqueValues) = 1, MAX(SplitValues), "Mix")

 

1. In Power BI Desktop, go to your data model and add a new calculated column.
2. Paste the formula in the formula bar.
3.  The new column will now categorize each entry as either the single fruit name if all components are the same, or "Mix" if they differ.

 

This formula splits each 'Category' entry into its components, checks for uniqueness, and categorizes them accordingly. Adjust the delimiter in the `SUBSTITUTE` function if it differs.

Appreciate your Kudo 👍

    Hi InsightSeeker 

     

    As ThxAlot suggested, using Power Query to get the expected result will be easier. Otherwise if you have interest in a DAX solution, you can try below formula to add a calculated column into the current table. 

    Column = 
VAR string = SUBSTITUTE([Category], "-", "|")
VAR len = PATHLENGTH(string)
VAR splitCategories = 
    ADDCOLUMNS(
        GENERATESERIES( 1, len),
        "mylist", PATHITEM( string, [Value] ) 
    )
VAR Categories = SUMMARIZE(splitCategories,[mylist])
RETURN
IF( COUNTROWS(Categories) = 1, MAXX(Categories,[mylist]), "Mix")

    Thanks to the solution from DAX how split a string by delimiter into a list or... - Microsoft Fabric Community

      Hello Anonymous - I am getting the below error when using this DAX

       

      The arguments in GenerateSeries function cannot be blank.

        I have attached a sample pbix. Hope it would be helpful. 

         

        Do you have any rows that may have blank or empty values in the Category column? This may cause this error.
