Calculating maximum time between two records

Hello, I have a dashboard that I use for statistics on incident reports. I use a measure to calculate the working days between today and the last incident posted in my database. Here's the measure...

    Yea my bad, as _incidents is a virtual table inside the same expression, DAX expects column references without the table name.

    If you want to also include the time between the last incident and today, we will have to add some more variables inside the measure. Just append this to the existing variables and replace the RETURN row:

    VAR last_incident = MAXX( FILTER( Incident, Incident[TypeAccident] = "AT" ), Incident[DateAndTime] )

VAR last_vs_today =
    COUNTROWS(
        FILTER(
            Dates,
            Dates[Date] > last_incident &&
            Dates[Date] <= TODAY() &&
            WEEKDAY( Dates[Date], 2 ) < 6
        )
    )

RETURN MAX( _max, last_vs_today )

Hi timalbers , your solution worked witth a little tweek on the MAXX measure.

 

Here's the final measure :

Measure = 
VAR _incidents =
    ADDCOLUMNS(
        FILTER( Incident, Incident[TypeAccident] = "AT" ),
        "prev_incident",
        CALCULATE(
            MAX( Incident[DateAndTime] ),
            FILTER(
                ALL( Incident ),
                Incident[DateAndTime] < EARLIER( Incident[DateAndTime] ) &&
                Incident[TypeAccident] = "AT"
            )
        )
    )

VAR _max =
    MAXX(
        _incidents,
        COUNTROWS(
            FILTER(
                Dates,
                Dates[Date] > [prev_incident] &&
                Dates[Date] <= [DateAndTime] &&
                WEEKDAY( Dates[Date], 2 ) < 6
            )
        ) 
    )

RETURN _max

 

I would like to add a small modification.

 

For the moment, it shows the highest count of working days between two incidents.

 

But when the highest count is between the last incident and today, it still show the highest count of working days between two incident.

 

Do you think it's possible to add this in the measure.

 

Again thanks for your help and have a nice day.

 

BR,

 

Philippe
