Measure Performance Issue: Running Total

[New_be]

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]

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

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 

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

Sorry i cannot share my report.
Yupp. I dont see any issue with my code either. For X-axis, i use date.

BTW, thanks for for remarks! really appreciate it 😊
