Hi @Anonymous,

You can try to use the below measure formula to get and compare with the max quantity based on category groups and use the 'if statement' to replace the not match row values to zero.

formula =
VAR currQuantity =
    MAX ( Table[Quantity] )
VAR maxQuantity =
    CALCULATE (
        MAX ( Table[Quantity] ),
        ALLSELECTED ( Table ),
        VALUES ( Table[Category] )
    )
RETURN
    IF ( currQuantity = maxQuantity, currAmount, 0 )
