Hi ppvinsights 

 

Try this, if still too slow we can try Power Query

PauseNextIndex = 
IF (
    FaktPascomQueueLog[verb] = "PAUSE";
    VAR curIdx = FaktPascomQueueLog[Index] 
    RETURN
    CALCULATE(
        MAX( FaktPascomQueueLog[Index] );
        ALLEXCEPT( 
            FaktPascomQueueLog; 
            FaktPascomQueueLog[agent]; FaktPascomQueueLog[queue] );
        FaktPascomQueueLog[Index] > curIdx;
        FaktPascomQueueLog[verb] = "UNPAUSE"
    );
    BLANK ()
)

      Hi ppvinsights 

       

      No problem, it is considered best practice to do your column, table transformations in Power Query, in your case the number of rows and the type of the calculation probably was hard on the engine.
