The second column is a calculate column with other table. However, I need to create a mesure to display the sum of prices of last month. For exemple, we are in June 2022, I want see my sum of sales of May 2022. My DAX measure need to calculte the sum for the period between 01/05/2022 and 31/05/2022. Or it depends of the months with 30 or 29 days. I don't want to select data in order to I have automaticaaly measure when the month change, for exemple, in July 2022, I want see the sum of sales of June 2022 and in Septembre 2022, I want see the sum of sales of August 2022.

Thanks in advance.

Hi, @PBIBeginner2022 
If you have a calendar, write something like this:

CALCULATE(SUM('Table'[NUMBERPRICE (€)]), PREVIOUSMONTH('Calendar'[Date]))

Hi @vojtechsima ,

When I use my table "calendar" (it's a table with date of all of days between  1988 and 2030), it's wrote "vide" or "blank" in english ... I don't see the value of what I want calculate.

@PBIBeginner2022  DO you have a slicer that picks a certain value (date)? Are there data for the previous month in the selected date?

@vojtechsima  I don't have slicer on my sheet and they are data on previous month. I have data all months of all years

Can you use it in a visual with date column inside of that visual, let's say a Table and lemme know if that works?
