    Hi Anonymous,

     

    It looks like there existing more than one records where Action is set to "Set Priority to regular" per Ticket ID. If so, please try below suggestion. 

     

    First, add a calculated column in Table1.

    Index =
RANKX (
    FILTER ( 'Table1', Table1[TicketID] = EARLIER ( Table1[TicketID] ) ),
    Table1[Action date/time],
    ,
    ASC,
    DENSE
)

    Then, add measure [Average] into a card visual.

    Timediff =
VAR _CurrentActiontime =
    SELECTEDVALUE ( Table1[Action date/time] )
VAR _NextActiontime =
    CALCULATE (
        SELECTEDVALUE ( Table1[Action date/time] ),
        FILTER (
            ALLEXCEPT ( Table1, Table1[TicketID] ),
            Table1[Index]
                = MAX ( Table1[Index] ) + 1
        )
    )
VAR diff =
    IF (
        SELECTEDVALUE ( Table1[Action] ) = "Set priority to regular",
        DATEDIFF ( _CurrentActiontime, _NextActiontime, SECOND ),
        BLANK ()
    )
RETURN
    diff

    Average =
    AVERAGEX ( ALLSELECTED ( Table1 ), [Timediff] )

    Best regards,

@AIB Yes i mean exactly what you are saying. With giving a priority to a ticket i indeed mean the action set priority to regular in the example table. And i indeed want the time between when 'Action' is set to "Set priority to regular" and whatever comes immediately afterwards that for a specific ticket ID. I want to give you all the sample data that you need, but i don't know what data you want extra besides the example table that i allready posted above.

And how would the average have to be calculated exactly? Is it the average of that period of time you just described across all TicketIDs?

    Yes exactly, something like this: - Ticket A took 5 minutes between the set priority and following action - Ticket B took 3 minutes between the set priority and following action - Ticket C took 15 minutes between the set priority and following action The average has to be the average of 5, 3 and 15 minutes Many thanks for your help.

      Try this measure in a card visual for instance:

       

      AvgTimeCreation2Priority =
VAR _AuxTable =
    SUMMARIZECOLUMNS (
        Table1[TicketID];
        "Time2Next";
        VAR _CreationTime =
            VALUES ( Table1[ Ticket created] )
        VAR _NextActiontime =
            FIRSTNONBLANK (
                CALCULATETABLE (
                    VALUES ( Table1[ Action date/time] );
                    Table1[ Action date/time] > _CreationTime
                );
                1
            )
        VAR _TimeDiffMins = ( _NextActiontime - _CreationTime )* 24 * 60
        RETURN
            _TimeDiffMins
    )
RETURN
    AVERAGEX ( _AuxTable; [Time2Next] )

      where Table1 is the name of your table. Do note that the result is in minutes (ex.  2 mins 30 seconds will show as 2,5). You can convert that into mins:secs format if you so need.

        This looks great and when i use it on a card visual i get data. The only doubt i have is, does this use the rows with "set priority to" as start date/time? Maybe it's my beginner knowledge of PowerBI but i don't understand how this measure does that.
