Power bi previous date if blank
Hi, I have 2 different tables, one date table 'Datum"[Date] and one table showing a quantity 'T_Part[InvQty] on a certain date of a certain partcode 'T_Part[Partcode]', both tables are related by date. If a date is not shown in table T_Part I want it to look up the last InvQty of that part. In this case 15-12-2021 until 21-12-2021 should display 759.70, 25-12-2021 and further should display 687.28. I have found many topic about this but can't find anything that works for me.
If someone could help me out it would be great!

ddijstelbloem 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
