Count Rows Falling between two dates ( from disconnected table )

[sagar512]

Hi,

I am having two disconnected tables ( Task and Ticket).

On Task Table I need to count tickets (from the Ticket table) that fall between the task created date and Created +90 date.

In Excel, I used the below formula to get the expected output.

how can calculate the same in dax?

Task Table
Task Number	Category	Created	Created +90
Task 1	A	1-Jan-21	1-Apr-21
Task 2	A	1-May-21	30-Jul-21
Task 3	B	1-Sep-21	30-Nov-21
Task 4	B	1-Jun-21	30-Aug-21
Task 5	B	1-Dec-21	1-Mar-22

Ticket Table
Ticket Number	Created
Ticket 1	7-Jan-21
Ticket 2	2-Feb-21
Ticket 3	2-Feb-21
Ticket 4	6-Jun-21
Ticket 5	10-Jun-21
Ticket 6	19-Aug-21
Ticket 7	9-Sep-21
Ticket 8	13-Jun-21
Ticket 9	3-Mar-21
Ticket 10	9-Sep-21

@sagar512  try this measure

Measure =
CALCULATE (
    COUNT ( 'Table 2'[Ticket Number] ),
    DATESBETWEEN (
        'Table 2'[Created],
        MAX ( 'Table 1'[Created] ),
        MAX ( 'Table 1'[Created +90] )
    )
)

I added a category column into my data and this measure needs the lowest level (task number) to work.

it's not working as expected if I remove the task number.

the calculation should always work on task level and then aggregate per report context 

Any way we can achieve this?

@sagar512  what do you mean?

[sagar512]

I get below; If I remove the lowest level and add category

  I still don't see an issue here 

 You need to display 

'Table 1'[Created] and 

'Table 1'[Created +90] in the viz for the DAX to evaluate in the filter context. Without having that axis present, the expression will not evaluate.

 

But if you do want to have that one displayed without bringing

'Table 1'[Created] and 

'Table 1'[Created +90]

then you need an index column and do this with a new measure

I think this is what the exact challenge is; to make this measure work without including task number or date (lowest level) into the viz.

I am using powerbi dataset, so I can't even make this work using the calculated column.

@sagar512  for some reason, my previous reply got edited and I have edited back my original reply. Please take a look above.

It is not an issue, it is doable. Check the new measure.

[smpa01]

@sagar512  when you are asking a question can you pleae make sure to include all the components? Do you wan to revise the previously provided sample data and include this new component?

[sagar512]

Added the new column to the data (original post). 

[smpa01]

@sagar512  can you provide some sample data

[sagar512]

For some reason I don't see a way to attach powerbi file; so added my tables to the original post.

will this help?

Hi,

Here is one way to do this:

Dax (calculated column):

Tickets = calculate(COUNT(Tickets[TN]),DATESBETWEEN('Calendar'[Date],'Task Table'[Created],'Task Table'[C90]))

Data model:
End result:

I hope this helps and if it does consider accepting this as a solution and giving a thumbs up!

[sagar512]

Thanks for the response; but unfortunately I cannot use the calculate function in the column, as I am working with powerbi data set (direct query). 

Any way to do this in measure?

[ValtteriN]

Hi,

It works almost exactly the same with a measure: 

tickets_ =

var _sdate = max('Task Table'[Created])

var _edate = max('Task Table'[C90]) return

calculate(COUNT(Tickets[TN]),DATESBETWEEN('Calendar'[Date],_sdate,_edate))

[sagar512]

thanks, but the problem with the above solution is I need to always keep the lowest level (Task number) into the context.

my end goal is to build some chart that aggregates to month level etc, but calculation should always stay at task number level and then aggregate.

I think the column was the best fit in this scenario but unfortunately, I can't use it due to direct query 😞
