Ranking measure with Table variable

Hello Folks, 

 

I'm trying to create measure for Top 10 customers based on sales amount in Power BI which is connected Live to the Tabular model.

 

Customer is Dimension and Sales amount is in fact table and I need to Rank the customers from 1 to 10 based on highest sales amount for each customer.

 

I have tried to create this DAX query below but this gives me Rank '1' for all the rows, I am guessing this has to do with filter context.

Measure =
var _top10 =
TOPN(10, FILTER(SUMMARIZE(all('Fact'), Customer[Name],"Total_Sales", SUM('Fact'[Sales Amount])), [Sales Amount] >0 ), [Sales Amount])
 
RETURN
COUNTROWS(FILTER(_top10, [Total_Sales] >= EARLIER([Total_Sales]))
)
I have also tried using RANKX but it gives performance issues.
 
Any help or guidance is really appreciated.
Thanks

    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.
