Calculating number of non unique values

[zoveress]

Hello,

I am being puzzled with a solution here. I have a table with 2 columns, one of them shows the date when the date snapshot was taken the other shows a process if it was running:

If all 3 processes are running at the same time we can say that the application is 100% available, if only 2 or 1 processes running we can say that the application is not available. I would like to see an output like this:

9/12/2017 1:13:00 PM | 3

9/12/2017 1:14:00 PM | 3

9/12/2017 1:15:00 PM | 3

9/12/2017 1:16:00 PM | 1

9/12/2017 1:17:00 PM | 1

9/12/2017 1:16:00 PM | 1

9/12/2017 1:18:00 PM | 1

Any help would be greatly appreciated.

You want DISTINCTCOUNT: https://msdn.microsoft.com/en-us/library/gg492142.aspx

I got that far myself I just do not know how to group the counts by date?

Just create a table visualization and put your date and your measure in it. It will group automagically. Or, you could use SUMMARIZE to create a new table.

I actually have 1470 unique dates. I need all of them grouped. I need a new table with the 1470 unique dates and the number of processes active at that time next to them. By the way I am new to this so any help code-wise would be appreciated. Like this:

9/12/2017 1:13:00 PM | 3

9/12/2017 1:14:00 PM | 3

9/12/2017 1:15:00 PM | 3

9/12/2017 1:16:00 PM | 1

9/12/2017 1:17:00 PM | 1

9/12/2017 1:16:00 PM | 1

9/12/2017 1:18:00 PM | 1

...... 1470

In SQL you would use count and groupby but what is the syntax for DAX?

Hi @zoveress,

Based on your description, I think summarize function will suitable for your requirement.
Use the data column as the group column, then summary stats column by distinct count function.

Table formula:

Summary table= SUMMARIZE('Table','Table'[DateTime],"Distinct",DISTINCTCOUNT('Table'[Status]))

Many thanks for the answer we are half way there. Now it creates a list of dates but doesn't count the processes correctly. It counts 3 even if only one process was running at that time. Any ideas? 🙂

Oh sorry my bad I used a different table for the second value, it works now with the following formula:

Summary table =  SUMMARIZE('CALC_CaptureDateList','CALC_CaptureDateList'[Date],"Distinct",DISTINCTCOUNT(CALC_CaptureDateList[Process]))

Many thanks for the help!
