Date switch with one period seems to not show right results

[GiulianoCi]

Hello, 

I've been trying to solve this issue, but w/o success, tehrefore I came here for help. 

My main issue is concerning the date differnce in past (year, month etc.) tyo ompare witrh current values. 

I have uploaded 2 types of files:

• one raw data from an excel file where the data is already structured (from monthly level to daily level) "13" raw data"
• one in which I try to take monthly figures and divide them via a working days table: "13" daily - w formula" in which I divide the Monthly volues to CUD or working days.

Now, when I try to bring the figures from 2022 to 2023, in case of raw data it works and brings all the correct figures, but in case of defined formula, e.g.: for measure 13" daily - w formula, the dateadd measure brings some different figures. altough the calculations gives the correct daily figures. 

I have attached a picture to show exactly how it looks (also the PBI file):

In case of W01 from 2022 w have for measure "13" -> 1373 pcs which both versions calculate corect, but the date add brings different values: 1373 for raw data and 1600 for formula data. 

P.S.: same behavior is also if I use SAMEPERIODLASTYEAR measure.
