Community ChampionSAMEPERIODLASTYEAR(DATESYTD( )) different from DATESYTD(SAMEPERIODLASTYEAR( ))??
Hi all, This came up as I was trying to answer this post by hbolo (no need to read it to answer this question). Here is the pbix We have a Date table with dates between 01/01/2018 and today (Jan 3...
This is just another case where the Time Intelligence functions don't work as expected because the Date table is wrong.
Remember: Time Intelligence functions are guaranteed to work *only* if the Date table is "complete" - meaning you need all the dates until the end of the year.
Not doing that, what happens is that the year 2019 seems made by 15 days, so if you include all of them than it seems you have an entire month, or an entire year.... You are violating the assumption made by Time Intelligence and you cannot trust any result at that point.

Very interesting
I remember you found a bug before as well :smileywink:
I am not sure why this is happening
but if we use following we get correct results even with the last date.
YTDPreviousYearRevenue =
CALCULATE (
SUM ( Revenue[Revenue] ),
SAMEPERIODLASTYEAR ( DATESYTD ( 'Date Table'[Date].[Date]) )
)
