Challenge with SUM of AVERAGES

Anonymous — Wed, 25 Nov 2020 14:33:14 GMT

Hello PBI Community!

So, I have a challenge with DAX. My end-users want to see AVERAGE of products sold for each weekday but the Grand Total should be a SUM of these AVERAGES. I wrote some DAX:

So my code looks like that:

    sumOfAverages = 
VAR avgFull =
CALCULATE (
SUM ( [sold_qt] )
/ DISTINCTCOUNT ( [delivery_date] )
)
RETURN
IF (
HASONEVALUE ( [weekday_name] ),
avgFull,
SUMX ( VALUES ( date_weekday_dim[weekday_name] ), avgFull )
)

Actually it's working only if I have selected all the weekdays. See the screen below. If I select something on slicers and there won't be any data from particular weekday it looks like that.

So the Grand Total is not correct. I think that there's a problem with SUMX (VALUES ... )) section in DAX but really don't know how to figure it out.

Could you help me with this, please?:)

Hi Anonymous ,
Created a table, then on visuals a slicer, and a matrix, then a measure.

Sum of Daily Averages = SUMX(DailyAverages,Divide(DailyAverages[Sold],DailyAverages[DistinctCount]))

This should work if I understand your issue.

Let me know if you have any questions.

If this solves your issues, please mark it as the solution, so that others can find it easily. Kudos 👍are nice too.
