findout date difference between two dates and non dates
Community ChampionMahamoodBi First part is easy, it is
Measure =
( MAX([TermDate]) - MAX([ServiceDate]) ) * 1.2nd part:
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

MahamoodBi I can't provide you with a specific solution without sample data to build a model out and code it. Sorry, having trouble following, can you post sample data as text and expected output?

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.
