I have a Fact table that looks like this (it's a really small table... I know the design is less than ideal!!!):

CREATE TABLE DiagnosisFact(
PatientID INT,
SymptomName VARCHAR(20),
Severity TINYINT,
ConsentDate DATE
);

I have a Symptom table...
CREATE TABLE DimSymptom (
SymptomName VARCHAR(20) PRIMARY KEY
);

I can create the DiagnosisCount ... COUNTROWS('DiagnosisFact').
The dumb thing I can't get to work is the Percentage of Total stuff. I must be missing something, but I can't override the SymptomName on the column or row...

I thought it should be:
Pct of Total:=
DIVIDE( [Diagnosis Count], CALCULATE ( COUNTROWS('Diagnosis'),ALL('Diagnosis'[SymptomName]) ) )

but no joy... what am I doing wrong?

For grins, I did this in Excel 2016, and it worked...
=CALCULATE ( [Total Sales], ALL( 'Calendar'[EnglishMonthName] ) )

In terms of this dataset, it would be
= DIVIDE ( [Diagnosis Count], CALCULATE ( [Diagnosis Count], ALL( 'Diagnosis'[SymptomName] ) ) )
thanks,
Pieter

I figured it out...
DIVIDE( [Symptom Count],
CALCULATE(COUNTROWS('Diagnoses'),ALL('Diagnoses'))
, BLANK()
)


One day I might maybe understand DAX, but that's not going to be anytime soon.

I guess my question would be, why are you using PowerPivot for this calculation to begin with? Why not "just" use T-SQL?

Jeff,
I would but then I would lose the ability to drill into it. It's the smallest data warehouse structure ever! 3 dimension tables and a fact table. Not terribly exciting, but I'm learning DAX, so I'm starting small.

Besides, if I did it all in SQL Server, I'd never learn DAX at all...
