YTD weekly calculation

Hi everybody,

I have a measure to calculate the YTD (year to date, since 1st January) service availability of different business process. This measure is as follows:

 

  • YTD Weekly Availability = ( (Total Elapsed Operating Time – Total Down Time) / Total Elapsed Operating Time)

Total Elapsed Operating Time = (DATEDIFF("01/01/2024",NOW(),SECOND)

 

Currently that measure is used in a table to show the current service availability for the different business processes.  Please see Picture attached 

 

 

Now I want to show the trend of YTD by week, considering the time reference on the last day of the week (each Sunday).

I have managed to calculate the time elapsed operating time ( in an running total way) from January 1st to each Sunday of the elapsed weeks. I know the down time of each process for each week; however I am no able to properly calculate the running total of elapsed down time for each process (from 1st January to each Sunday of the elapsed weeks.

 

Please find attached picture 

Summing up,  I don´t find the proper DAX calculation for the running total of elapsed down time. I always get the total down time for the week, not the accumulative running total

 

Thanks for your help or suggestions

    Anonymous , Based on what I got, Have date table, joined it with Date part of your datetime column.

    If needed create a table in you column

     

    Date = Datevalue([datetime Column]) // join with date of date table 

     

    Have week created column in date table

     

    Have these new columns in Date Table, Week Rank is Important in Date/Week Table
    Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
    Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
    WeekDay = weekday([Date],2)

     

     

    Use them in visual

     

    And use measure

     

    YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))

      Hi amitchandak 

      Thanks a lot , but it´s not working.

      The measure is given me the Running Total up to now, but when adding to a visual a putting the weeks in the colum visual table , it keps giving the down time by week instead of the running total until each week.... so I have the same wrong calculation, YTD for each week not the running total YTD. 

      Please see the difference between Power BI calculations and Excel calculations
