Time representation with DATEDIFF

Hi all !   I'm stuck on this one for good. Here is my problem on PowerBI. I have a sensor, that sends to the DB its state "Marche"(On) or "Arrêt"(Off). When the state change, it sends a new row, wi...

    With this you get all dates required ?

     

    Tables des Dates Intervalles = 
VAR DateDebut=MIN('TF GRA 700 (2)'[Date de début])
VAR DateFin=MAX('TF GRA 700 (2)'[Date de début])
VAR TabDates=SELECTCOLUMNS(CALCULATETABLE(Dates,
                DATESBETWEEN(Dates[Date],DateDebut,DateFin)),
                "Dates TF",Dates[Date])
RETURN TabDates

     

    Then you need to add column(s), but depends on what you want.
    If you want the total hours per day or make difference by machine...

     

    Next step could be something inspired by that :

    Tables des Dates Intervalles = 
VAR DateDebut=MIN('TF GRA 700 (2)'[Date de début])
VAR DateFin=MAX('TF GRA 700 (2)'[Date de début])
VAR TabDates=SELECTCOLUMNS(CALCULATETABLE(Dates,
                DATESBETWEEN(Dates[Date],DateDebut,DateFin)),
                "Dates TF",Dates[Date])
VAR TabDates2=CROSSJOIN(TabDates,'TF GRA 700 (2)')
VAR TabDates3=ADDCOLUMNS(TabDates2,"Valeur",IF([Dates TF]>='TF GRA 700 (2)'[Date de début]&&[Dates TF]<='TF GRA 700 (2)'[Date de fin],1,0))
RETURN FILTER(TabDates3,[Valeur]=1)

    This could be done with less lines but at least it is step by step.

    You should have a table with that with all dates and a column to select only dates you are interested in.

     

    Hope this helps

Hi,

You're right, PBI doesn't propose a time format for duration that goes over 24h. But it's quite easy to format it if needed. In your case I don't think so, but otherwise you could use :

//This measure is formatting a time in H M S
VAR HoursCalc=TRUNC(SUM(TabXXX[TotalTime]),0)//Take the whole number part for hours
VAR MinutesCalc=ROUND((SUM(TabXXX[TotalTime])-HoursCalc)*60,0)//Remain is minutes
VAR HourseCalc2=IF(LEN(HourCalc)=1,"0"&HeureCalc,HeureCalc)//Add prefix 0 to H
VAR MinutesCalc2=IF(LEN(MinutesCalc)=1,"0"&MinutesCalc,MinutesCalc)//Add prefix 0 to mn
RETURN
IF(ISBLANK(HoursCalc2),BLANK(),HoursCalc2 & " h ") & IF(ISBLANK(MinutesCalc2),BLANK(),MinutesCalc2 & " mn")

In your case I think you need to create a table dynamically to store your values, with something like this :

CALCULATETABLE(DateTable,
    DATESBETWEEN(DateTable[Date],StartDate,EndDate)

This should create a Date Table with the values you need, and to add to it your column with your calculated time, have a look at :

https://community.powerbi.com/t5/Desktop/CALCULATETABLE-ADDCOLUMNS-SUMMARIZE-multiple-columns-can-not-be/td-p/878350

This should do the trick.

 

Let us know...

I'm not sure to understand... 
I think here are the limits of my comprehension 🤔

 

I stripped my pbix of any sensitive data, and uploaded it :

Could you develop a bit more your idea of the dynamic table and the link your make with the hours per day ? 

Thank you !
