YTD uptime using measures

Hi,

 

I have several equipment (wells) which should run 24hrs per day on various facilities.

To define the overall uptime for each facility, I'd like to know if at least 1 one of them has been running for 24 hrs.

I have a dataset where per item the running hours are recorded.

When using the following measure;

max_hrs_well = Calculate(max([running_hrs]),[facility_ID]),

this gives me for each the day the correct value. (See screenshot below)

 

However when I want to create a cumulitive of the hrs to track the performance YTD, doesn't 'just' add the current day with the previous day. I have tried sumx and maxx, but these formulations give me the original number.

 

Also I have created an additional if-measure, and then try to sum it with;

Cumulative = calculate (max_hrs_well, datesytd [ date])

But this does add the values on consecutive days.

 

While writing this post, I think I can also add a column to my dataset, but I'd rather implement a correct measure.

I have also searched the forum, but I feel like some solutions are just too complex.

 

Thanks in advance!

    For anyone following this topic, I have solved it myself.

     

    I added a column to my table which finds the maximum uptime of the wells based on a facility filter.

    Then with the calculate function I create an average over this value.

    Using the filter for the current year only, it shows the average YTD.

    Not sure if this is the most robust solution, but it works.

     

    If anyone is interested in more details of these explanation, just let me know.

    GerlofVisser , In datesyd and the date in the visual both should come from a date/calendar table.

    example

    YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD('Date'[Date],"12/31"))
Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd('Date'[Date],-1,Year),"12/31"))

     

    To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

      Thanks for your quick answer amitchandak , I tried answering yesterday, but an error occured...

       

      Just to clarify a bit, I do have a date table and it's linked correctly, but I think the issue has to do with the max function.

      This is my measure for checking whether the facility was up and running for 24hrs:

       
      max hrs well = CALCULATE(MAX(energy_unit_data_fdc_value[hrs_online]),energy_unit_data_fdc_value[EU_ID])
       
      Then for the cumulative I use the following function, but that doesn't seem to work.
      Cumulative hrs online = CALCULATE([max_hrs_well], DATESYTD(Rolling_Calendar[Date])) also the adjustment
      Cumulative hrs online = CALCULATE([max_hrs_well], DATESYTD(Rolling_Calendar[Date], "12/31")) does not work.
       
      I have also tried to use a SUMX and MAXX, but this doesn't work either;
      Uptime_Field = SUMX(energy_unit_data_fdc_value,MAXX(energy_unit_data_fdc_value,energy_unit_data_fdc_value[hrs_online]))/[Wellcount]
       
      The wellcount (=amount of wells) statement is added, otherwise the value is the multiplication of the (amount of wells) times  "max_hrs_well"
       
      Any advise is appreciated.
       
      Regards,

        GerlofVisser , Do you max of row level data or sum till month level and then do max . If you can explain by a data example
