DAX

Cyriackpazhe — Wed, 05 Mar 2025 05:39:00 GMT

In the first measure, I'm trying to compute the average quarterly sales and next measure the average montly sales in each year. In the first mesure, i should be getting the year level value in the quarter level as well since there is an ALL function around the quarter column, but why am i getting this result. Same issue with the second measure. Any reason why this is happening

Hi Cyriackpazhe try this version for your measure

Quarterly Average Test =
AVERAGEX(
VALUES('Calendar'[Date]),
CALCULATE([Total], ALL('Calendar'[Date]))
)

But what was the error with what i wrote??

It was supposed to give the result as expected right

Hi Cyriackpazhe

measure might aggregate values across all quarters rather than respecting the context of year and quarter

Hi Cyriackpazhe,

Thank you for reaching out to the Microsoft fabric community forum. Thank you some_bih, for your inputs on this issue.

Thank you for bringing this to my attention. Upon reviewing your DAX measures, I noticed the inconsistency in average quarterly and monthly sales across different periods, even with the ALL() function applied.

This occurs because ALL('Calendar'[Quarter]) or ALL('Calendar'[Month]) only removes the filter for that specific column. However, in a matrix visual with a hierarchy (such as Year > Quarter or Year > Month), the row-level filters from the visual still affect the context, resulting in varying outcomes for each row.

To ensure the calculation is performed at the year level and the same value is displayed across quarters or months in the matrix, you can use the following DAX measures with ALLEXCEPT, which retains only the Year filter:

Quarterly Average:

DAX CopyEdit Quarterly Average = CALCULATE ( AVERAGEX ( VALUES ( 'Calendar'[Quarter] ), [Total Sales] ), ALLEXCEPT ( 'Calendar', 'Calendar'[Year] ) )

Monthly Average:

DAX CopyEdit Monthly Average = CALCULATE ( AVERAGEX ( VALUES ( 'Calendar'[Month] ), [Total Sales] ), ALLEXCEPT ( 'Calendar', 'Calendar'[Year] ) )

ALLEXCEPT clears all filters from the Calendar table except for Year, so the average is always calculated at the year level just as intended. This approach avoids row context interference from the visual (like month or quarter rows).
