Power BI Hour Difference between two different rows from different column with a condition

sushmitasur4 This is a variation on Previous Row. 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/339586.
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

Can you post your data as text and provide the expected output?

Or maybe it's simple and you can just do this:

Measure = SUMX( FILTER( 'Table', [Type] = 3 ), [End] - [Start] )

Then convert to seconds and use Chelsie Eiden's Duration? Chelsie Eiden's Duration - Microsoft Fabric Community
