Overlaps per month

Hi all,
I have a table with tickets and I need to find out how many blocker tickets were open at the same time per month.

TicketIDCreatedResolvedPriority
101.04.202101.04.2021Blocker
201.04.202103.04.2021Standard
305.04.202131.06.2021Blocker
407.04.202111.04.2021Blocker
515.05.202120.05.2021Blocker

 

So the result should be:

  • 04.2021: 3 tickets (ID 3, 4 & 5)
  • 05.2021: 2 tickets (ID 3 & 5)
  • 06.2021: 1 ticket (ID 3)

Found some measures for overlapping values, but they always count per ticket and not by month, or the ticket always counts for the month it was created, but should be counted in every month it was open.
Thanks in advance,
Greetings Patrick

  • Hi Patrick_BT ,

     

    You'll need to create a calendar dimension table. There's plenty of examples online either in DAX or Power Query (recommended). Your calendar table will need at leaste Date and Month/Year (MM.yyyy).

     

    Once you have that, the basic measure structure for your counts would be something like this:

     

    _openTickets =
    VAR __maxDate = MAX(calendar[date])
    VAR __minDate = MIN(calendar[date])
    RETURN
    CALCULATE(
      DISTINCTCOUNT(yourTable[TicketID]),
      yourTable[Priority] = "Blocker",
      FILTER(
        yourTable,
        yourTable[Created] <= __maxDate
        && yourTable[Resolved] >= __minDate
      )
    )

     

     

    Use calendar[YearMonth] and [_openTickets] in your visual.

      Hi Pete,


      thanks, I have created the calendar table and the measure already looks good.

       

      Is it possible to extend it so that not all tickets from e.g. 04.2021 are counted, but only the maximum number of concurrently open tickets?

      Ticket ID 1 is currently also counted although there was no overlap with the other tickets in April.


      Many greetings
      Patrick
