Row % DAX

[quipmaster]

Hello DAX Experts,

I am having a little trouble making DAX work as I envision it.

My expected result is the top table - Built-In Function.

For my bottom table, I am using DAX to have more control

My DAX is 

Able % of Row Total = DIVIDE(

COUNT(

Able[Ability]),

CALCULATE(

COUNT(

Able[Rating] ) ,

ALL(Able[Ability])))

However, the Total column is not 100%, but 12.5%. Also, the row percentages are different.  

I am not a community super user, so I can only post this link to the spreadsheet  https://docs.google.com/spreadsheets/d/16V_02xrT1Xi1SLbigs11q14EgIfQCtUVW1efR7axk-M/edit?usp=sharing as opposed to a PBIX. All nudges are greatly appreciated.

Thank you,

Hi @v-xiaotang ,

Yes, you are spot on. I think my Power BI might be buggy. I am going to reach out to MS. The best my IT team can do is maybe upgrade my version.

I sincerely appreciate your guidance.

Hi @v-xiaotang and @tamerj1 ,

I've found the issue.  Sorting Rating by Rating Number is the issue.

Rating is a conditional column to allow sorting Rating numerically instead of alphabetically. But it seems to have an unintended side effect with DAX. The % is made 100% across the table.

When Rating is sorted by Rating, % is across the rows - my intended outcome. 

For etiquette, it would make sense to post a new question about sorting and DAX, correct?

I appreciate your guidance so very much.

Thank you for your guidance.

I found the last piece of the puzzle.

I found a solution.

Able % of Row Total =

DIVIDE (

    COUNT ( Able[Ability] ),

    CALCULATE ( 

        COUNT ( Able[Ability] ),

        ALL ( 'Able'[Rating], 'Able'[Rating Number] )

    )

)

To have the sort column not interfere with the DAX, rating number must be added to the ALL statement.

The calculation works as envisioned.

Hi @quipmaster 
I hope this is what you're looking for

Able % of Row Total = 
DIVIDE (
    COUNT ( Able[Ability] ),
    CALCULATE (  
        COUNT ( Able[Ability] ),
        ALL ( Able[Rating] ) 
    )
)

Hi @tamerj1 ,

That is exactly what I am trying to do.

Thank you for adding the PBIX file. 

I think my Power BI might be buggy. I am puzzled as to why I get 100% in all the rows. Your PBIX file works exactly as I envision. My IT is not well versed in Power BI debugging. Maybe I should notify MS.

At any rate, thank you very much!

@quipmaster , Why are taking the rating below?

Like ?

Able % of Row Total = DIVIDE(
COUNT(
Able[Ability]),
CALCULATE(
COUNT(Able[Ability] ) ,
removefilters(Able[Rating])))

Hi @amitchandak,

Thank you for your reply. Maybe these two tables will better explain my logic.

With the Total Abilities per Rating DAX, I want to figure out a way to divide Rating by Sum responses. For examples, Analyze data to measure success and extremely difficult has one response. 1 response divided by 161 responses equals 0.62% not .08%. 

I tried the DAX I think you recommended.  This is the output.

Please let me know If you have any questions.
