M Power Query Column Calculation

Adding a new Custom Column.

Want to calculate the number of days to DUE_DATE

 

= Table.AddColumn(#"Changed Type", "DaysToDueDate", each DateTime.LocalNow()-([DUE_DATE]))

 

This is producing resuts that look like   4.88499E + 13

 

DUE_DATE is DATE type.  I want the difference between these two date to produce an integer simply telling how many days remain.

    Hi Anonymous 

     

    It doesn't have to... This is my complete code:

    let
    Origen = Excel.Workbook(File.Contents("C:\example.xlsx"), null, true),
    Hoja1_Sheet = Origen{[Item="Hoja1",Kind="Sheet"]}[Data],
    #"Encabezados promovidos" = Table.PromoteHeaders(Hoja1_Sheet, [PromoteAllScalars=true]),
    #"Tipo cambiado" = Table.TransformColumnTypes(#"Encabezados promovidos",{{"DUE_DATE", type datetime}, {"Column1", type text}}),
    #"Personalizada agregada" = Table.AddColumn(#"Tipo cambiado", "DaysToDueDate", each Duration.Days(DateTime.LocalNow()-([DUE_DATE])))
in
    #"Personalizada agregada"

     

    I have used an excel with this data and it is working perfectly:

    Column1 DUE_DATE
    aaa 14/11/2023 11:35
    bbb 21/11/2023 18:10
    ccc

    18/11/2023 13:45

     

    I haven't defined any type for the new column but it shows correctly the result. I think your problem is with some "naming" or missing punctuation...

      Thank you for the reply and link. However, I'm receiving an error "Changed Type Not Recognized. Make Sure It's Spelled Correctly".  Any idea what's causing that

        Hi Anonymous 

        Have you put a "," in the Power Query Editor before the step (I mean, at the end of the previous sentence)? If so, are you sure the previous step name is "Changed Type"?

        Please, check all these things and tell me if it works or not
