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 run...

    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 :

Appreciate your Kudos.

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,
Gerlof

    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

      Hi, 

       

      I have created a quick excel example, but this is what I want to achieve.

      amitchandak 

      OwenAuger , I have seen your posts, maybe you can help as well?

      Hope that this helps.

       

      Thanks!

        Ok, I have created some additional measures and am trying to get it right, but I think the issue lies with summing up measures.

        I have also tried to summarize the column I am creating in mutiple steps in one formula, this looks something like:

         

         

        Uptime_Field = SUMX(
SUMMARIZE(energy_unit_data_fdc_value, Facility_Lookup[Facility_ID],"Max Hours", if((CALCULATE(max(energy_unit_data_fdc_value[hrs_online]),Facility_Lookup[Facility_ID]))=24 , 1 , (CALCULATE(max(energy_unit_data_fdc_value[hrs_online]),Facility_Lookup[Facility_ID]))/24)),[Max Hours])

         

         

        My original approach was the following:

         

        With this measure, I am finding the max of all the wells which belong to a certain facility ID, this gives me a good result.

         

        max hrs well = CALCULATE(max(energy_unit_data_fdc_value[hrs_online]),flowID_Lookup[FACILITY_ID])

         

         

        With the following measure I am normalizing the data on a daily basis

         

        Uptime_Field_day = if([max hrs well]=24,1,[max hrs well]/24)

         

         

        And this measure "Uptime_Field_Day" gives exactly the same results as the "Uptime_Field" measure.

         

        When I then use the YTD function to calculate the cumulative, the results are the same.

         

        Cumulative hrs online = CALCULATE([Uptime_Field_day], DATESYTD(Rolling_Calendar[Date]))
