Greetings:
I need a visual depicting, by date and group, the sum of values rolled up on customerID, but only the values where the transactionID is max for that month (since the accountbalance is calculated cumulatively in the data, so I only need the final one) and a difference calculated between that value, and the same calculation for the previous month.
I have been trying to combine different measures to accomplish this and playing aroudn with the DATEDIFF function, but we only started using PowerBI and DAX a week ago and its all still new to me.
Here is an example of the Input data (the yellow ones are the rows that should be filtered and calculated)
The final result should look like this.
I have already received some help in creating the first 3 columns in a calculated table, before the month-1 and difference became a requirement (thanks to @Razwan )
I would be most appreciative of any help in this regard.
Solved! Go to Solution.
Hi @Anonymous ,
Try the measures:
Max_transID =
CALCULATE(
MAX(Input[TransID]),
ALLEXCEPT(
Input,
Input[Date],Input[Group],Input[CustID]
)
)
SUM_value =
CALCULATE(
SUM(Input[Value]),
FILTER(
Input,
Input[TransID] = [Max_transID]
)
)
SUM_Month-1 =
CALCULATE(
[SUM_value],
DATEADD(Input[Date], -1, MONTH)
)
Diff =
IF(
[SUM_Month-1] <> BLANK(),
[SUM_value]-[SUM_Month-1],
BLANK()
)
(You enter a wrong data, right? which should be 150, not 180?)

Hello,
Sorry for the late response.
If you don't have a separate Date column, I would suggest creating one in the Result table (this one will help achieving the value for last month).
So, create a column like:
DateFormat = DATEVALUE([Date])
It will format your current YYYY-MM column into first date of that respective month.
Then, the measure Total LM:
Total LM =
CALCULATE(
SUM( Result[Total] ),
DATEADD( Result[DateFormat], -1, MONTH ),
ALL( Result[Date] )
)
And the Difference:
Difference =
VAR dif = SUM( Result[Total] ) - [Total LM]
RETURN
IF( ISBLANK( [Total LM]), BLANK(), dif )
Finally, just drag the Total LM and Difference measures into Result table and it should be fine.
However, in the future, I would suggest (as @amitchandak mentioned) using a dedicated Date table for a better use of time intelligence functions.
Please let me know how it works.
Kind regards,
Razwan
In case you have date, or can convert month into dates, you can easily make time intelligence work for you
MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last MTD (complete) Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))
You can take diff
diff= [MTD Sales] -[last MTD sales]
in your month format
Date = date(year(left(month-year,4)),month(mid(month-year,5,2),1)
To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s.
