Top 10 with Multiple Columns

Hi, 
Please follow a 5 steps process:

1. Get the Rank of NOC Colum like this: 

NOC_Rank =

    RANKX(

        ALL(TicketData),

        TicketData[NOC Completed Rate (Within 24 hours)],

        ,

        DESC,

        Dense

    )

2. Get the rank of FTR column:

FTR_Rank =

    RANKX(

        ALL(TicketData),

        TicketData[FTR Percentage],

        ,

        DESC,

        Dense

    )

3. Combined the ranks: 

Combined_Rank = [NOC_Rank] + [FTR_Rank]

4. Get the final rank:

Final_Rank =

    RANKX(

        ALL(TicketData),

        [Combined_Rank],

        ,

        ASC,

        Dense

    )

5. Finally, you can get a new table as follows:

Top10Table =

    FILTER(

        ALL(TicketData),

        [Final_Rank] <= 10

    )

I hope this will solve your problem.
