DAX PREVIOUSMONTH()

[Andy83]

Hi All, 

I have the following Query within Power Automate at the moment. I need the red parts below to be dynamic so it collects the previous months data. 

FILTER(
KEEPFILTERS(VALUES('Dates'[Date])),
AND('Dates'[Date] >= DATE(2024, 6, 18), 'Dates'[Date] < DATE(2024, 7, 18))
)

I thought something like this might work. I thought about maybe using the MONTH function someone and minus 1. Any help would be much appreciated. Thanks

FILTER(
KEEPFILTERS(VALUES('Dates'[Date])),
AND('Dates'[Date] >= DATE(PREVIOUSMONTH()), 'Dates'[Date] < DATE(TODAY()))
)

Hi @Andy83 - you can try the below measure for previous month's data without manually updating 

CALCULATE(
SUM('YourTable'[YourColumn]),
FILTER(
KEEPFILTERS(VALUES('Dates'[Date])),
'Dates'[Date] >= STARTOFMONTH(EOMONTH(TODAY(), -1)) &&
'Dates'[Date] < STARTOFMONTH(TODAY())
)
)

Hope it works for you.
