It was really helpful. 

You mentioned that this is one of your favourite DAX patterns. Could you please share your post or article with your other favourite DAX patterns?

vyacheslavg I'm having trouble with this unless I'm going mad I have created a very simple calculate DAX measure with an or filter and it's not working properly. 

 

I know the result is:

1001 = 36

1002 = 13

both = 49

 

My measure is: 

Members follow up or regular appointment = CALCULATE(DISTINCTCOUNT('Appointments'[Member]),
FILTER(
    'Appointments',
    'Appointments'[Type]="1001"||'Appointments'[Type]="1002"))

And the measure result is 36.

 

HELP!

    Hi  @vyacheslavg,

     

    I'm using a very similar DAX measure in Desktop with slightly different syntax. I seem to get the correct number (created around 50 records). Please let me know if I'm missing something:

     

    Members follow up or regular appointment = CALCULATE(DISTINCTCOUNT(Appointments[Members]), FILTER(Appointments, Appointments[Type] = "1001" || Appointments[Type] = "1002"))

    Hi @vyacheslavg DISTINCTCOUNT is expecting to return a single value in a calculated measure. What is the end result/visual you need the information in? This can easily be done in a table or other visuals without DAX.

     

    Thanks,

    dtartaglia Hi, so the distinctcount is counting unique instances of a member id, where the appointment type for the same row is 1001 or 1002.

    This is because there are hundreds of appointments for each member and I want to count unique members who have had at least one appointment. 

     

    Thanks!

    Hi dtartaglia 

     

    No, you're not missing something - I was. Clearly, I have members with an appointment with BOTH codes hence it's not adding the 13 and 36 exactly. I was expecting 49 but your example shows me what is actually happening here. 

     

    Thank you so much, I really appreciate it! :-)
