Measure Performance Issue: Running Total

Hi expert!

 

I have a measure performance problem to calculate a running total.


First Measure:

First is, i have a total man days calculation. Function of this measure is to count [Leave Entitlement];
*Leave entitlement consist of: annual leave (AL), Emergency leave (EL) and so on.

  

Total Man days = COUNTA( 'Leave Table'[Leave Entitlement] )
   
 
 
Second Measure:
This measure is to calculate running totals of man days or i called cumulative of total man days.
 
Cumulative Total Man Days =
   VAR maxDate = MAX('Calendar'[Date])
   VAR result =
      CALCULATE(
            [Total Man Days],
            FILTER(
                ALL('Calendar'[Date]),
                'Calendar'[Date] <= maxDate
   )
)

RETURN result


What happen when i implemented the second measure inside a visual?
Its worked, but Its load very very very slow. Can someone tell me why?

*In visual below, i take second measure over [date]

Need Help

    Hi New_be 

    I don't see any glaring issue with your code.

    1) Can you share the pbix by any chance?

    2) What are you using in the x-axis of the chart, Calendar[Date]?

    3) Why are you using COUNTA instead of COUNT. Try these changes:

          

           Total Man days = COUNT( 'Leave Table'[Leave Entitlement] )

     

    Cumulative Total Man Days =
VAR minDate =
    MINX ( ALL ( 'Calendar'[Date] ), 'Calendar'[Date] )
VAR maxDate =
    MAX ( 'Calendar'[Date] )
VAR result =
    CALCULATE (
        [Total Man Days],
        DATESBETWEEN ( 'Calendar'[Date], minDate, maxDate )
    )
RETURN
    result

    Have you used tried the changes I suggested?

    Another option would be to use week or month in the axis to reduce the number of calcs

    Hi New_be ,

     

    Your formula looks quite simple. You could try to modify the second formula as below and see if there's any improve to the speed.

    Cumulative Total Man Days =
   VAR maxDate = MAX('Calendar'[Date])
   var tmp_table = FILTER(ALL('Calendar'[Date]),'Calendar'[Date] <= maxDate)
   VAR result =
      CALCULATE(
            [Total Man Days],
             tmp_table
)

     

    Best Regards,

    Jay
