 The measure I have tried, but did not worked as expected.

CALCULATE([Sales_Measure],  FILTER(ALLSELECTED(DimDate), DimDate[Date] <  MAX(DimDate[Date])))

=
CALCULATE (
    LASTNONBLANKVALUE ( DimDate[DateKey], [Sales_Measure] ),
    DimDate[DateKey] < MAX ( DimDate[DateKey] )
)

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

@PBI_enthusiast2 Try:

PD Measure =
  VAR __DateKey = MAX('DimDate'[DateKey])
  VAR __PDKey = MAXX(FILTER(ALL('DimDate'),[DateKey] < __DateKey)
  VAR __Result = CALCULATE([Sales Measure], 'DimDate'[DateKey] = __PDKey)
RETURN
  __Result

DAX is easy, CALCULATE makes DAX hard...

Hi @Greg_Deckler and @CNENFRNL.  Could you share the way to solve this with the new WINDOW() and INDEX() functions.

Thank you.

No comments as I haven't mastered these newly introduced functions. I'm personally no fan for these funcs because they (seem to) sabotage the conciseness and elegance of "old-school" DAX funcs; IMHO they seem to be some replica of Tableau table calculation funcs.
