## Creating DAX measures for current and previous calendar month

I'm having trouble with this!

I have a measure to Count unique Invoices where the invoice status is "Submitted". I need this measure for the current reporting month and the previous reporting month. So I am thinking EOMONTH(TODAY()-1) and EOMONTH(TODAY()-2) would work.

However, whenever I add the EOMONTH filter, my measure produces entirely the wrong number. When when I add the -2 for Previous Month, it produces an identical figure to Current Month.

Any ideas?

``````Claims Current Month =
CALCULATE(
DISTINCTCOUNT(
'DataMart'[Invoice Id]),
FILTER('DataMart',
'DataMart'[Invoice Status]="SUBMITTED"
&&
MONTH('DataMart'[Invoice Date])=EOMONTH(TODAY(),-1)
))``````

Hi @heytherejem ,

If you only want to calculate the counts of "current month", "last month", "last before month "  by using the Dax, you could try the formula below.

``````Claims Last Month =
VAR current_month =
MONTH ( TODAY () )
RETURN
CALCULATE (
DISTINCTCOUNT ( 'DataMart'[Invoice Id] ),
FILTER (
'DataMart',
'DataMart'[Invoice Status] = "SUBMITTED"
&& MONTH ( 'DataMart'[Invoice Date] ) = current_month - 1
)
)``````
``````Claims Last Before Month =
VAR current_month =
MONTH ( TODAY () )
RETURN
CALCULATE (
DISTINCTCOUNT ( 'DataMart'[Invoice Id] ),
FILTER (
'DataMart',
'DataMart'[Invoice Status] = "SUBMITTED"
&& MONTH ( 'DataMart'[Invoice Date] ) = current_month - 2
)
)``````

I cannot see why this isn't working, I did try a VAR myself with no change to the total, what it's giving me is the grand total but not the total for the month in question. I add a minus two to the end of the measure, and the number doesn't change.

I have the month split in a matrix so I know what numbers I should be getting.

I can't upload a sample dataset to this forum as I don't have the option.

Hi @heytherejem ,

You need to have a cloud storage such as Onedrive or Google Drive where you can put your file. After that, you create a shareable link that you can insert in your post enabling people to download the file.

think it should be

``MONTH('DataMart'[Invoice Date])=Month(EOMONTH(TODAY(),-1))``

My personal preference is datesmtd. 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 MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date Filer],-1,MONTH))))
last year MTD (complete) Sales =  CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date Filer],-12,MONTH))))``````
