ALL Function - Mystery?
Sean,
Maybe it's related to some obscure cross-filtering issue from Payments to Asset to Location.
What do you get if you try:
County Total =
CALCULATE ( [Total Net], ALLEXCEPT ( Payments, Location[County] ) )Wow folks I figured it out! :smileyhappy:
AnonymousMystery solved!
The culprit was a Conditional Column created in the Query Editor
That Column was called Category Sort and I basically used it so in charts the Categories show in order of importance and not A-Z
If anyone wants to see what actually happens just follow these steps:
1) Load all 3 sample tables I posted on Page 1
2) Write these 2 Measures
Total Net = SUM ( Payments[Net] ) County Total = CALCULATE ( [Total Net], ALL ( Payments[Subcategory], Payments[Category] ) )
3) Create a Matrix with County, Category and Subcategory in the Rows and then add the 2 Measures to the Values
Everything works great!
4) Now click Edit Queries and Add a Conditional Column in the Payments Table =>Category Sort
you can use the UI and basically
if Category is Cat 2 then 1, else if Category is Cat 3 then 2, otherwise 1 => OK => Close and Apply
so far so good nothing is affected yet!
5) Now go to the Data View => Payments table
=> select the Category Column => click Sort By Column => select the Category Sort column
6) Now go back and look at the Matrix => the County Total Measure no longer works as intended
HAPPY NEW YEAR!!! :smileyhappy:

Sean,
Nice detective work. That still seems like a bug to me.
- Yes this is an annoying problem with "sort by column" in Power BI (but not PowerPivot).
Discussed here in one of the DAX Puzzles
http://www.sqlbi.com/daxpuzzle/unexpected-filter-behavior-in-calculate/ Good point. So not a bug, but a poorly documented feature/ side-effect/ use case... Now that we know with hindsight what to look for, it's simple! Also documented nicely here: https://blog.crossjoin.co.uk/2015/12/15/power-bi-desktop-sort-by-column-and-dax-calculations-that-use-the-all-function/
I wonder what we can do to avoid the next group also spending hours trying to figure out such an obscure issue?
