    Hi sqlguru448 ,

     

    Be aware that making a summarizaition of a full table will bring for sure performance issues, in your case you are using the FACT table that I assume have a huge number of data so be aware of that.

     

    Try the following code:

     

    Measure = 
var temp_table =
        FILTER (
            SUMMARIZE (
                ALLSELECTED ( Customer[Name] );
                Customer[Name];
                "Total_Sales"; [Sales Amount]
            );
            [Sales Amount] > 0
        )

var Ranking = RANKX(temp_table; [Sales Amount])


RETURN
    Ranking

     

     

    Then filter out all rankings above 10.

HI  sqlguru448 

Try to use this formula to create a measure

Measure 2 = 
VAR  _RANK= RANKX (
        ALLSELECTED ( Customer[Name] ),
        CALCULATE ( SUM ( 'Fact'[Sales Amount] ) ))
RETURN
IF ( _RANK <= 10,  _RANK)

 

if not your case, please share some simple sample data and your expected output.

 

Regards,

Lin
