LAST MONTHS SALES

MONA4980 — Thu, 24 Jul 2025 21:41:36 GMT

Hello,

I am really new to Power BI and DAX. I am trying to get MOM data and have to first get my profit from last month.

Before I throw it out there know that I have a table that uses the calendar table and I have to use DAX to create that relationship. that is the first part of the function. When I add the second part it does not return any values. the dispdate is a short date format.

No errors but no results either.

What am I getting wrong?

LAST MONTH PROFIT = CALCULATE(SUM('ORDERS'[PROFIT]),USERELATIONSHIP('Calendar'[Date],'ORDERS'[DISPDATE]), PARALLELPERIOD('ORDERS'[DISPDATE], -1, MONTH))

Hi,

1. Mark your calendar table as Date table.
2. Use time-based functions like 'PARALLELPERIOD' on your Calendar table.

That said, update your Measure to,

LAST MONTH PROFIT =
CALCULATE(
SUM('ORDERS'[PROFIT]),
USERELATIONSHIP('Calendar'[Date], 'ORDERS'[DISPDATE]),
PARALLELPERIOD('Calendar'[Date], -1, MONTH)
)

Hope this works for you:)
