Dax ALL function Performance Problem

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...

@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.

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.

Pat
