Solved

Display time over 24 hours in Power BI

Hello

 

I'm having a little challenge in a simple table trying to calculate the time passed, for example from 22:00 to 2:00 in the morning.

 

I have tried this code to calculate the Duration in Minutes it works as long as the times are on the same day, otherwise, it gives me a negative minutes.

 

I would also like to ask power bi to change the Shift end Date to the next day if it goes past midnight.

 

I am hoping someone can help me.

 

 

Thanks

    Use below formula for minutes calculation

    Duration in Mintes = ([Shift end Date]-[Shift start Date])*1440

      Hello Vijay,

       

      Thanks for the formula but 

      It's still the same problem when the time bleeds over past 12 am into the next day

      I would also like to create a new date time that correctly shows the next day for these records. I just merged the date and the end date because I didn't now how to create and end date column and time column any other way.

        The shift can't end before the shift starts. This issue will lead to data inconsistency.

        Assuming the intention to put this data is correct, then you can use below formula

        =ABS([Shift start Date]-[Shift end Date])*1440

    Hi Vijay

     

    I didn't have a Start Datetime or End Datetime column to work with. I had to try and create these columns. 

     

    This is the only data 

    That is the beginning of my problem. I didn't have a start date/time column or End date/time. I tried to create both columns using power query using the column merge with a space. Using the Date and Start and then the Date and End. This end column isn't correct for the ones that are past 12 am should go to the next day. 
     
     
    If I could create a good End Date Time column, using the Hours but I didn't know how to do that. 
     
    Would you know how I can do that?
     
    Thank you kindly for your help

      It looks like that your shift ends next day. You will need to create Start Datetime and End Datetime like these in PQ

      =[Date]&[Start]

      =Date.AddDays([Date],1)&[Start]

      Then in PQ, you can use following formula for Total Minutes

      = Duration.TotalMinutes([EndDateTime]-[StartDateTime])

      See the working here - Open a blank query - Home - Advanced Editor - Remove everything from there and paste the below code to test

      let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjTUNzIAIiNDJR0gx8rE1MrAQCHAF8izALJAHEdfpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Start = _t, End = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Start", type time}, {"End", type time}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "StartDateTime", each [Date]&[Start], type datetime),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "EndDateTime", each Date.AddDays([Date],1)&[End]),
    #"Added Custom2" = Table.AddColumn(#"Added Custom1", "TotalMinutes", each Duration.TotalMinutes([EndDateTime]-[StartDateTime]))
in
    #"Added Custom2"
