Filtering a constant value

[afbraga66]

Hello,

I am new to Power BI, so my question is that why this measure example returns 3 rows in a table, while I expected it to return only 1 row. I do not understand how to filter constant values.  Thank you.

Best regards,

André

Hi， @afbraga66 ，
According to offical document, CALCULATE(<expression>[, <filter1> [, <filter2> [, …]]])

https://docs.microsoft.com/en-us/dax/calculate-function-dax

Calculate ([column]) or average or count... as 1 is a constant.so we could change it to:

Measure = IF(MAX('Dim_PLANT'[Plant_Code])="P058",1)

The final show:

Or 

Measure 2 = CALCULATE(COUNT(Dim_PLANT[Plant_Code]),FILTER('Dim_PLANT',[Plant_Code]="P058"))

The final show:

You are calculating 1, in whatever case.

It gives you back 1.

If you calculat a measure like countrows(table), and the countrows filter by case

then it will get different numbers.

Ok. Please try

SUMX (
VALUES ( PlantCode ), 

IF ( PlantCode = "p058", 1 )

)

@tamerj1 Ok, that works. I'll try to apply that concept to what I really have to do. That was just an example to express the idea of what I was trying to do. Still, can you explain why the other methods do not work? Thank you.

CALCULATE replaces the filter with the new filter inside it. So it replaces P051 with P059 and so on for all plant codes. What I don't understand why the KEEPFILTERS function didn't work with constant value as it KEEPFILTERS keeps the original filter and the intersection between the old the new filter leaves blank tables at all plant codes except P059. 
With SUMX we manually return blank if the code is not P059

Hi @afbraga66 

try replace FILTER with KEEPFILTERS but delete table name reference

Same, doesn't work.
