Calculer la différence entre deux mois

[Anonymous]

Hello,

I am trying to calculate the difference between the current month and the previous month.

To calculate the number of rows in my table I use the following formula:

#Deskphone & Fax = CALCULATE(COUNTROWS(UOP),FILTER(UOP,UOP[Deskphone & Fax]="Deskphone & Fax"))
It gives me a lot of value
But I can't find how to calculate and display the difference between the current month and the previous month.
I am attaching two screenshots for information.

Hi @Anonymous ,

Please try:

Difference = 
VAR _current_month = [#Deskphone & Fax]
VAR _previous_month = CALCULATE([#Deskphone & Fax],PREVIOUSMONTH('Calendar'[Date]))
VAR _result = _current_month-_previous_month
RETURN
_result

and drag the 'calendar[Year],'calendar'[month] and the measure into the table visual.
