Slicer and DAX Column not working

[huguest]

Hello,

I have a "Date" table and a "Cases" table that are not linked. 

I created the following DAX Column in my "Date" table to return the number of Cases reported to date (based on count of IDs) and it is working fine.

Column= CALCULATE ( DISTINCTCOUNT( 'Cases'[ID]), FILTER('Cases','Cases'[Reported On] <= 'Date'[Date] ))

If I add a filter for the Department as follows, it still works as expected:

Column = CALCULATE ( DISTINCTCOUNT( 'Cases'[ID]), FILTER('Cases','Cases'[Reported On] <= 'Date'[Date] && 

'Cases'[Department] = "Business Technology" ))

I am trying to replace the Department condition with a slicer that will allow me to select any available Department, but it is not working.

I tried the following with a slicer visual that cotains the 'Cases'[Department] field:

Column= CALCULATE ( DISTINCTCOUNT( 'Cases'[ID]), FILTER('Cases','Cases'[Reported On] <= 'Date'[Date] && 

'Cases'[Department] = SELECTEDVALUE('Cases'[Department]) ))  

I also tried creating a new "Department" table with all the possible values and adding is as a slicer with the following:

Column= CALCULATE ( DISTINCTCOUNT( 'Cases'[ID]), FILTER('Cases','Cases'[Reported On] <= 'Date'[Date] && 

'Cases'[Department] = SELECTEDVALUE('Department'[Department]) ))  

Any help would be appreciated.

Hugues.

Hi , @huguest 

Looks like my reply was a little late. But it's great to hear your problem got resolved!

It's true that it's better to use measure rather then calculate columns here.

I also make a demo here: pbix attached
