    Hi mnarmeen,

    >>The id e,g 878 is repeating again and again

    TOPN function returns the top N rows of the specified table. When you use [itemQty] to filter the report, it returns all the top 5 rows based on [itemQty], it did't care the customer ID if is same.

    For your requirement, please create a measure get the sum of each customers.

    sum=CALCULATE(SUM(entries[itemQty]),ALLEXCEPT(Custom, Custom[ID]))


    Then create another measure used to filter the top 5 customers.

    RANK=RANKX(ALLSELECTED(Custom),[sum],,DESC,Dense)


    Finally, create a table visual, select the [ID], measure [sum] as value levels. Add the measure [RANK] as Visual level Filters, let the RANK value is less than or equals to 5, please review the following screenshot.

    Thankyou so much for the help. However I got it resolved by making a measure

     

    sumItemQty=sum(enteries[itemQty])

     

    and then used it in CustomerID filtering topN. 

     

    Yet, I dont know why it didnt work by simply puting ItemQty column in CustomerID topN and using SUM in aggregation.

Hi mnarmeen

 

Given that I understand your data model and what you want to achieve, there is several ways to go about this.

 

Personally, I like to use LOOKUPVALUE() to gather all the data, which I want to slice on, in one table, when I have tables, which aren't all related to eachother. I'll elaborate on this later on.

 

Could you provide a screenshot of what you have now, and maybe tell a little more about how the data is stored?

 

Let me know, if you want me to elaborate on anything.

 

Best,

Martin

        In what table is the "ItemQty" column?

         

        It's important that you use columns from the same table when making the TOPN.
