Cumulative total for previous month using custom non-date slicer

[KrisD]

Hi!

Have been struggling with this for a long time now. 😞

I have current week, current month, previous week and previous month as a custom slicer in a disconnected table and one measure

to return results for each of the chosen periods. Everything works except for Previous month. 

The part of the entire code which corresponds to Previous month below.

This link contains the sample file with all info needed, Sample file 

SELECTEDVALUE ( 'Period slicer'[Period] ) = "Previous month",
VAR MaxDate =  
    EOMONTH ( MAX ( Period[Date] ), -1 ) //Returns the last day of previous month, 2021-12-31
VAR LastMonth =
    EOMONTH ( MaxDate, -1 ) + 1 //Returns the first day of previous month, making the period 2021-12-01 to 2021-12-31. The variables return the correct timeframe, but do not work in the visual.
RETURN
CALCULATE (
    [Number of loaded tonnes], 
        ALL ( Period[Date] ),
            Period[Date] <= MaxDate,
            Period[Date] >= LastMonth
          )

@KrisD , You can use date table and time intelligence

refer example

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]))
next month Sales = CALCULATE(SUM(Sales[Sales Amount]),nextmonth('Date'[Date]))
this month = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH('Date'[Date])))
last MTD (complete) Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-1,MONTH))))
previous month value = CALCULATE(sum('Table'[total hours value]),previousmonth('Date'[Date]))

Hi, thanks for your quick reply! 

However I do not get the desired results from the code.

CALCULATE ( 
    [Number of loaded tonnes],
    DATESMTD (
        ENDOFMONTH ( 
            DATEADD ( Period[Date], -1, MONTH )
        )
    )
)

@KrisD , for previous month cumulative use only datesmtd with date add

CALCULATE ( 
    [Number of loaded tonnes],
    DATESMTD (
         
            DATEADD ( Period[Date], -1, MONTH )
            )
) 

Endofmonth will give complete month on all dates

Thank you so much, looks like it works !! 

Will definitely save your code examples, have obviously been overthinking the way I calculate these kind of measures. 

As a side note, are you able to explain to me why my code with the EOMONTH variables do not work the way I thought they would?
