Double data

[alexandrerich]

Hi, 

I want to find how many hours trailers is at my warehouse.   In my document I know when a driver come whit a trailer and when is go out whit different trailer. 

In my PowerBI, I find how to calculate hours, but I want to filter trailers was already gone. 

Do someone have any suggestion, 

Thank's

@alexandrerich Not certain but seems like MTBF-type of problem. See my article on Mean Time Between Failure (MTBF) which uses EARLIER: http://community.powerbi.com/t5/Community-Blog/Mean-Time-Between-Failure-MTBF-and-Power-BI/ba-p/3395....
The basic pattern is:
Column = 
  VAR __Current = [Value]
  VAR __PreviousDate = MAXX(FILTER('Table','Table'[Date] < EARLIER('Table'[Date])),[Date])

  VAR __Previous = MAXX(FILTER('Table',[Date]=__PreviousDate),[Value])
RETURN
  __Current - __Previous

Might help with sample data as text and explanation of which column is which.

Hi Greg, , 

The problem is my trailer OUT and IN is not in the same line.  See example

Date IN	Trailer In	Trailer Out	Date out
2021-09-11 8:00	4834	4828	2021-09-12 8:00
2021-09-12 8:00	1546	1836	2021-09-13 8:00
2021-09-12 8:00	4823	1546	2021-09-13 8:00
2021-09-12 8:00	1625	75189	2021-09-13 8:00
2021-09-12 8:00	61413	4834	2021-09-13 8:00

And I dont want see trailer was go out. 

I find how to have how many hour trailers is here at the present time, But I want to erase trailers is gone.

Hi @alexandrerich ,

You can use merge.

1.Duplicate the main table out of a new table, then retain the ID and time of the old table, and retain the ID and time of the new one, and then merge.

2.Then expand the table

3.Then add custom column to calculate the difference.

4.Convert the column to total hours.
