DAX: Rollup value within a group

Hi Community,   I've one question, maybe a silly one, but I already wasted some time trying to solve the following requirement...   I've the following very simple star schema model in my PBI file...

    Hi lacq

     

    First add a calculated column in your FactValues

     

    Use this Column in the Visual

     

    CountryName = related(DimCountry[CountryName])

     Now you can use this MEASURE to get the Cumulative

     

    Cumulative =
CALCULATE (
    SUM ( FactValues[Value] ),
    FILTER (
        ALLEXCEPT ( FactValues, FactValues[CountryName] ),
        FactValues[Date] <= SELECTEDVALUE ( FactValues[Date] )
    )
)

Excellent Zubair_Muhammad, it works like a charm.....  Well done!!!!

 

Now imagine that I've another group by, e.g.  City_Name... how can I change the DAX to manage it, i.e.

 

 

Thanks in advance, lacq

    I think you just need to replace CountryName with CityName in DAX.

      Hi Zubair_Muhammad,

       

      I'm sorry I didn't explain myself well.... when I said that I have a new "group by", City_name, I would like to maintain the Country Name Group... maybe the City_Name was a bad example... let's try with  ProductName, so the same product might be sold in different countries.. and I would like to roll up the value by Country_Name and Product_Name .

       

      Thanks again, lacq

        In that case, I believe you will just need to extend the

         

        ALLEXCEPT ( FactValues, FactValues[CountryName] )

         to

         

        ALLEXCEPT ( FactValues, FactValues[CountryName], FactValues[ProductName] )
