Count events between two dates

Hey there

 

I'm facing a situation where I must calculate how many occurrences (from the Fact table) took place between two dates (that also comes from my Fact table).

 

 

This is my fact table, and from here I must count how many transactions took place between the EventStart and EventEnd, but inserting this onto a matrix panel that contains a hierarchy-format date (from day > week > month > quarter > year). However, this must be calculated taking into consideration the end of the date in the row (e.g. 31 January, 2020 , 29 Feb., 2020 and so on). The next image has an example of what I must calculate, so on May/20, there were 128 active transactions, i.e., transactions that started before the last date of May, and lasted longer than the end of the month (128 transactions that started before May 31, 2020 and ended after May 31, 2020). Althoug I must calculate this by using the end of the month as a reference, my Calendar table uses the start date, so I'd say it's necessary to create a condition to return the end of month (MAX('Calendar'[Date]) or whatever date is selected on the hierarchy.

 

These numbers were created out of my imagination and does not stands for the actual calculation.

 

I've seen some posts like this one, but none of them had exactly what I aim to achieve. 

 

Here's the sample file.

 

(tamerj1 do you know how I could do that?)

 

 

Thanks in advance.

    This piece of code solved my problem:

     

    COUNTROWS(FILTER(ALL(Data), MAX('Calendar'[Date]) > [EventStart] && MAX('Calendar'[Date]) < [EventEnd]))

    Hi,

    I am not sure if I understood your question correctly, but I tried to create a sample pbix file like below.

    Please check the below picture and the attached pbix file.

     

     

     

    Active events count: =
COUNTROWS (
    FILTER (
        Data,
        Data[EventEnd] >= MIN ( 'Calendar'[Date] )
            && Data[EventStart] <= MAX ( 'Calendar'[Date] )
    )
)

      I might not have expressed myself clearly, so I'll try again (thanks for the feedback):

      In your example, in April 2022 your measure results in the number 3, however, it should've returned 9, because there are nine IDs that match my criteria, i.e., that started before April 30, 2022 and ended after April 30, 2022.

       

      EventStart date filter:

       

      EventEnd date filter: 

       

      Do you know what I should edit in order to achieve this result?

       

      Thanks in advance.

      Hi, is it possible in this example to count, how many and what ID's was active in each month ? To get table like this:

      Month-YearID'sActive ID's
      Jan-2021329672
      Jan-2021643151
      Feb-2021329674

    Hi Anonymous ,

     

    try this:

     

    VAR Open Events =
    SELECTCOLUMNS (
        GENERATE (
            Fact Table,
            DATESBETWEEN (
                'Date'[Date],
                Fact Table[EventStart],
                Fact Table[EventEnd] - 1
            )
        ),
        "TransactionID", Fact Table[TransactionID],
        "Date", 'Date'[Date]
    )
     
    RETURN
    COUNTROWS(Open Events)
     
    Please hit the thumbs up & mark it as a solution if it helps you. Thanks.

      sorry, instead of 

      RETURN
      COUNTROWS(Open Events)
       
      you must use
      DISTINCTCOUNT(Open Events[TransactionID])

      Unfortunely it didn't work. Using countrows I got a huge number and when I tried using Distinctcount, this error pops up:

      “The DISTINCTCOUNT function only accepts a column reference as an argument.”

       

      Thanks for your help, friend.
