    Hi FelippeAzevedo7 ,

     

    If you want the first item of a duplicate ticket to appear as a single one, you will also need a sort field to determine the order, such as date, etc.

     

    You can refer to the column expression below.

     

     

    Unique/Duplicate = 
    VAR CurIndex = 'Table'[Index]
    VAR MinIndex = CALCULATE(MIN('Table'[Index]),ALLEXCEPT('Table','Table'[Ticket]))
    RETURN
    IF(CurIndex=MinIndex,"Single","Duplicate")

     

     

    Did I answer your question? If yes, pls mark my post as a solution and appreciate your Kudos !

     

    Thank you~
