last data in colum

[ArienLans2020]

how can i make a colum whit the last data?

[Greg_Deckler]

Column = MAX('Table'[Date])

?

Otherwise, if you want the last row's date, then you would need an Index and then you could do this:

Column =
VAR __LastIndex = MAX('Table'[Index])
RETURN
MAXX(FILTER('Table',[Index] = __LastIndex),[Date])

[ArienLans2020]

I get an error on the last line.

column = 
VAR __LastIndex = MAX('2020 (2)'[2020 Lanstomaten])
RETURN
MAXX(FILTER('2020 (2)'[2020 Lanstomaten]=  __LastIndex),[Datum])

the colomn datum is a  

YYYYMD

date
