Data Transform in Power BI to Convert Time or date/time field to total number of minutes?

[Syndicate_Admin]

Hello Power World, 

I am trying to determine the throughput of a particular data transfer I am doing from on-premises to SharePoint Online.  After the import, I can extract an excel sheet of everything transferred and the amount of time each item took to transfer over.  I import this report into PowerBI.  One field is a time value field showing "hh:mm:ss".  

I would like to create a second column that expresses that in total number of minutes.

let
Source = Excel.Workbook(File.Contents("C:\Users\Me\OneDrive\myAggregate Summary Report -BATCH-1.xlsx"), null, true),
#"Aggregate Summary Report (10)_Sheet" = Source{[Item="Aggregate Summary Report (10)",Kind="Sheet"]}[Data],
#"Promoted Headers" = Table.PromoteHeaders(#"Aggregate Summary Report (10)_Sheet", [PromoteAllScalars=true]),
#"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Duration", type time}}),
#"Extracted Time" = Table.TransformColumns(#"Changed Type",{}),
#"Changed Type1" = Table.TransformColumnTypes(#"Extracted Time",{{"Migrated bytes", Int64.Type}, {"Total bytes", Int64.Type}, {"Migrated items", Int64.Type}, {"Total to be migrated items", Int64.Type}, {"Total scanned items", Int64.Type}, {"Items not migrated", Int64.Type}, {"Total GB", Int64.Type}, {"Migrated GB", Int64.Type}}),
#"durationMin" = Table.AddColumn(#"Changed Type", {{"durationMin", Int64.Type}, each Duration.TotalMinutes(Duration.From([Duration]))
in
#"durationMin"

I've looked at various posts and documents elsewhere, but I can't get this to work either because of syntax errors or too few arguments to a function.  I am a novice when it comes to DAX

Thanks!

Signed, 

Baffled and bewildered!

No, Excel stores time as a fraction of the day; the Data Model stores it as a proper datetime value. So unless you convert that value to a decimal number first, you can't get the minutes by x 1440 (which is easy to do though). In your case,

Table.AddColumn(PriorStepOrTableName, "Elapsed Time", 

each Duration.TotalMinutes(Duration.From(DateTime.From([Duration]))))

Your formula is erroring because you have only "{}" for your  parameters in your #"Extracted Time step. Also, your Table. AddColumn should be written as

Table.AddColumn(table as table, newColumnName as text, columnGenerator as function, optional columnType as nullable type) as table

Time is stored as a fraction of a day. So to express the value in Minutes, merely multiply by 1440 (or 24*60).

If you wanted time in seconds, you would multiply by 86,400.

Minutes = [Time]*1440

Note: The above formula is DAX and you would use it as an added column in Power BI.
