    Hi icdns ,

     

    I download you sample and have test. Firstly I suggest to to sort [Month] column by [MonthNo] column.

    For reference: Sort one column by another column in Power BI Desktop

    Then create a measure as below to achieve your goal.

    Sales Percentage = 
VAR _SUMMARIZE =
    SUMMARIZE (
        ALLSELECTED ( sampledata ),
        sampledata[Year],
        sampledata[Month],
        sampledata[City],
        "Sales", CALCULATE ( SUM ( sampledata[Sales] ) )
    )
VAR _ADDMAX =
    ADDCOLUMNS (
        _SUMMARIZE,
        "MaxSales", MAXX ( FILTER ( _SUMMARIZE, [City] = EARLIER ( [City] ) ), [Sales] )
    )
VAR _Sales =
    CALCULATE ( SUM ( sampledata[Sales] ) )
VAR _MaxSales =
    MAXX ( FILTER ( _ADDMAX, [City] = MAX ( sampledata[City] ) ), [MaxSales] )
RETURN
    DIVIDE ( _Sales, _MaxSales )

    Result is as below.

Hi Anonymous , 

 

Thank you for this. It is now working when it's on a monthly view. However, in my table I have also Quarter and Year column. If I drill up to yearly and quarterly view the value adds up. (Ex. If the view is Yearly, the value point let say 2016 is the TOTAL per unit of the 12 months (Jan-Dec))

 

The computation must be the same on how we compute with the monthly view wherein (Present value) ÷ (Maximum Data Point) 

 

How can we insert this in the dax? 🙂 

 

Thanks!
