Hi,
I posted a question on this forum a while back regarding getting 3 month rolling average data (answered by @Jihwan_Kim😞 Solved: 3 month rolling data visual - Microsoft Power BI Community
The attached .pbix was provided with the following DAX measure:
However this doesn't seem to be giving me the correct average values in the table visual:
.pbix file:
https://www.dropbox.com/s/gwid24yyo4isxtx/arslanmanzoor.pbix?dl=0
For example, for May 2021, task A, the raw data values are 42, 42, 42, so should give an average value of 42. However in the visual I am getting an average of 40.63.
Is there a mistake in the DAX formula?
Thanks in advance!

Hi @ArslanManzoor ,
The measure you are calculating is the average value of the previous 3 months in this case you are getting for may the values between February and April and making the average so the data is:
If you make the average you get the 40.63.
To what I read you want to have the values of the montlhy average on the last 3 month so you want that if the value is on the last 3 month show the average otherwise do not show.
Redo your measure to:
TimeTakenAverageValue =
VAR MaxFactDate =
CALCULATE ( MAX ( 'Calendar'[Date] ), ALL ( 'Calendar' ) )
VAR Edate =
EDATE ( MaxFactDate, -2 )
RETURN
SWITCH (
TRUE (),
SELECTEDVALUE ( AxisTable[Month & Year] ) = "Current",
CALCULATE (
[Time Taken Avg],
FILTER (
ALL ( 'Calendar' ),
'Calendar'[Month & Year] <> MAX ( 'Calendar'[Month & Year] )
)
),
MAX ( 'Calendar'[Date] ) <= MaxFactDate
&& MAX ( 'Calendar'[Date] ) >= Edate, CALCULATE ( AVERAGE ( Data[Time taken] ) )
)
check result below and in attach PBIX file.
