Problem with Previousmonth

Hi guys,

I need the dates of the previous month but using a different date than the current one for example the date of the last reload (5/3/2021)

I try using 

Month last reload = CALCULATE(PREVIOUSMONTH('Diagnostica'[Last reload]), MONTH('Diagnostica'[Last reload])-1)

Diagnostica is a table with 1 column and 1 row where is the date of the last reload.

It doesn't work. Can you help me please?

@giuliapiazza94 , in case you want to create a table then


table of last month =



if you need to measure use time intelligence with a date table 

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
last month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth('Date'[Date]))
