Hi All,
I'm telling you the scenerio with sample data. I'm unable to share
I created a measure on my report something like that.
Measure2 =
CALCULATE(
CALCULATE(
SUM('TABLE'[Measure]),
FILTER('TABLE',
'TABLE'[Dim1] = "A"
&& 'TABLE'[Dim2] = "X"
)
),
ALL('TABLE'[Dim3], 'TABLE'[Dim4])
)
I'm showing it like that.
This measure performance is terrible.
I have Dim3 and Dim4 as a filter on my page.
I don't want to make filter to my measure2 with this dimensions. Because of that I was used ALL function in my DAX formula.
The problem is starting over there.
If I don't use ALL function everything is fine.
As I understand my DAX works like that;
Firstly select the ALL context and than show us in table by 'Customer'
It was facing with performance issue because of that.
I need something like that,
Firstly it should get the customers and than start to calculate measure2.
How can i improve my DAX ?
Is there anyone have any idea ?
I'm sharing example pbix file. Actually it doesn't make much sense but anyways...
Solved! Go to Solution.
@Anonymous - Maybe try:
Measure2 =
CALCULATE(
SUM('TABLE'[Measure]),
FILTER(ALL('TABLE'),
'TABLE'[Dim1] = "A"
&& 'TABLE'[Dim2] = "X"
)
)
Very hard to troubleshoot without understanding your data and what you are trying to do. I have an couple articles on DAX Performance Tuning.

Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
Why do you have nested CALCULATE()? It shouldn't be necessary; you can put the ALL expression as another clause in the first/inner CALCULATE.
If this works for you, please mark it as the solution. Kudos are appreciated too. Please let me know if not.
