Filtering columns in a Matrix
Hi Necrosis1968, I assume you've built your matrix by dragging and dropping columns and then changing calcualtion to "Count (Distinct)". Is it correct?
If so, you're using "implicit" measures as commented by Greg_Deckler. "Implicit" means that PowerBI makes a calculation for you and you don't need to write any formula.
The reason you get 1 when filtering "Resolved" is because when apply it, your table is filtered only to 2 rows (Resolved = Yes) and each "Problem Type" has only 1 "Unique ID" at that moment.
What you might want to do is to "ignore" filter on "Resolved". To do so, you need to use "explicit" measures. The following measure will help you to achieve it:Count Unique ID = CALCULATE( //changes calculation context DISTINCTCOUNT( 'Table'[ UniqueID ] ), //perform this operation ALL( 'Table'[ Resolved] ) //but only when this rule is applied (nevertheless you see it a row below it applies before ) )Now, the filter "Resolved" is ignored so you get a proper count.
You can use the similar logic to calcualte resolved, unresolved cases as well as find the resolution percentage:Count Resolved = CALCULATE( DISTINCTCOUNT( 'Table'[ UniqueID ] ), 'Table'[ Resolved] = "Yes" ) Count Not Resolved = CALCULATE( DISTINCTCOUNT( 'Table'[ UniqueID ] ), 'Table'[ Resolved] = "No" ) % Resolved = DIVIDE( [Count Resolved], [Count Unique ID] )
Here is the final output:I'd suggest you to complete this course on YouTube before you going deeper in using PowerBI, it will help you a lot! Introducing DAX 101 videos (youtube.com)
Good luck 🙂

I was using count, rather than count distinct on Resolved. Otherwise, when we use more rows in the sample data, we would end up with 1 as the count as Resolved can only be Yes or No.
Thus a larger data set would look like:
Problem Type UniqueID Resolved
App A1 Yes
App A2 No
App A6 No
App A7 No
OS A3 No
OS A4 Yes
OS A8 Yes
With the desired output:
Problem Type Count of Unique ID Count of Resolved
App 4 1
OS 3 2
I tried the code you left, but it still doen't filter the Resolved column. I must be doing something fundamentally wrong.
Thanks for helping on the % which I'll attempt once the filter is working.
I'll start the YouTube link you suggested now! Thanks so much for the recommendation.
Also tried the % code but I get the error:
The syntax for 'Count' is incorrect. (DAX( CALCULATE( DISTINCTCOUNT( 'Table'[UniqueID] ), 'Table'[Resolved] = "Yes" )Count Not Resolved = CALCULATE( DISTINCTCOUNT( 'Table'[UniqueID] ), 'Table'[Resolved] = "No" )% Resolved = DIVIDE( [Count Resolved], [Count Unique ID] )))
I have changed my table name to Table so it all matches yours.
Not that the filtering works though.
Silly really as in excel you use a pivot table and add Resolved as a filter. That's what I'm trying to replicate.
Hi Necrosis1968, the block of my previous reply contains 3 separate measures 😉
Count Resolved = CALCULATE( DISTINCTCOUNT( 'Table'[ UniqueID ] ), 'Table'[ Resolved] = "Yes" )Count Not Resolved = CALCULATE( DISTINCTCOUNT( 'Table'[ UniqueID ] ), 'Table'[ Resolved] = "No" )% Resolved = DIVIDE( [Count Resolved], [Count Unique ID] )
