Backlog between Open Date & Closed Date

Hi  Anonymous ,

I created a sample pbix file(see attachment) for you, please check whether that is what you want. You can create a measure as below assume that there is a date dimension table in the model:

Backlog =
VAR _curdate =
    SELECTEDVALUE ( 'Date'[Date] )
RETURN
    CALCULATE (
        DISTINCTCOUNT ( 'Table'[Ticket Number] ),
        FILTER (
            'Table',
            'Table'[Start Date] <= _curdate
                && (
                    'Table'[Closed Date] > _curdate
                        || ISBLANK ( 'Table'[Closed Date] )
                )
        )
    )

In addition, you can refer the following links to get it.

Getting a running total of current open Tickets

CountOfOpenTicketsParamMeasure =
IF ( MAX ( 'Date'[Date]) <= MAX(Ticket[Opened] ),
COUNTROWS (
    FILTER (
        Ticket,
        Ticket[Opened] <= MAX('Date'[Date])  &&
            ( Ticket[Closed] > MAX('Date'[Date]) || ISBLANK( Ticket[Closed] ))
        )
)
)

Backlog- count a ticket in each month it is not solved

If the above one can't help you get the desired result, please provide more sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. You can refer the following link to upload the file to the community. Thank you.
