SAMEPERIODLASTYEAR without proper calendar

[Anonymous]

Hi Everyone!

Could you please help with the current problem:

I try to use SAMEPERIODLASTYEAR formula and my calendar has no any information about days (cause I get just monthly sales) and it looks like this (below it's just a part, I have 2020-2022 period). PERIOD_KEY - it's a date format I get from vendor, so I've created another 4 column to define year and month (first day of month). And when I try to use this formula nothing happens: 

LAST_PERIOD = CALCULATE([TOTAL_SALES_pack],SAMEPERIODLASTYEAR(Periods[Date]))

PERIOD_KEY	YEAR	Month	Date	Qrt	Month_№
202001	2020	Jan	01.01.2020	Q1	1
202002	2020	Feb	01.02.2020	Q1	2
202003	2020	Mar	01.03.2020	Q1	3
202004	2020	Apr	01.04.2020	Q2	4
202005	2020	May	01.05.2020	Q2	5
202006	2020	Jun	01.06.2020	Q2	6
202007	2020	Jul	01.07.2020	Q3	7
202008	2020	Aug	01.08.2020	Q3	8

Thank you in advance and hug you!:-)

@Anonymous , Use date table

LAST_PERIOD = CALCULATE([TOTAL_SALES_pack],SAMEPERIODLASTYEAR(Date[Date]))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
