## Per Unit Computation Dax

Hi Guys,

Would need your help in constructing a dax that computes the per unit computation. The computation of Per Unit is (Present value) ÷ (Maximum Data Point) I'm using a date hierarcy (Year, Quarter & Month) and other dimensions. So the maximum data point will depedend on the filters selected.

Expectation:

The maximum value for this is 999 (September) so we will divide each value by 999.

Example: 456/999 = 0.46

You can play with this Sample pbix: https://www.mediafire.com/file/0pbtogvc6kib02k/sample_powerbi.pbix/file

Thank you so much in advance!!

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] ) )
)
_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.

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!

Hi,

I hope you can get an idea on how to create a measure from the below picture and the attached pbix file.

``````Per unit measure: =
VAR maxcount =
CALCULATE ( MAX ( Data[Count] ), REMOVEFILTERS ( Data ) )
RETURN
DIVIDE ( [Count measure:], maxcount )
``````

@icdns , Assuming count is measure create a measure like this for denominator

Hi @amitchandak ,

that is what im planning to do. But the problem is i can't get the correct maxmium data point 😞
