Power BI Desktop: DAX expression to calculate the no. of rows in my Table for Last Month

[ajay_gajree]

No. of Breaches Last Month = CALCULATE(
                                COUNTROWS(Breaches),
                                PREVIOUSMONTH('Fiscal Calendar'[Date])
                                )

Hi All

I am trying to calculate the number of rows in my table for last month only using a measure.

My DAX above is returning Blank, when there is a number

Any obvious error? 

Thx in advance!

HI @ajay_gajree ,

You can try to use date function to manually defined date range filter instead to use time intelligence functions.

@ajay_gajree  - PREVIOUSMONTH needs to have an input (filter context). If you put your calculation into a table with months, No. of Breaches in Month (straight COUNTROWS calculation) and No. of Breaches Last Month, you will be able to compare the values. 

If you want to see the value in a card, you will need to filter/slice the page to the current month.

Hope this helps,

Nathan
