Help counting rows based on previous month date

[Anonymous]

Hey all,

In our Org we report 1 month in arrers. So I need to write a DAX measure that looks for "recorded date" for the previous month.

Im not sure what if any functions there are in PBI that evaluates current month? I need something to the effect of...

Last month Total = Countrows(This month - 1)

Thanks,

J

@Anonymous , Try with date table

MTD Sales = CALCULATE(countrows(Sales[Table]),DATESMTD('Date'[Date]))
last MTD Sales = CALCULATE(countrows(Sales[Table]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

Hey,

Not sure where to apply these? I have a date table and my data has a "date claim reported" column.

I am a noob to PBI

Hi @Jaydpie ,

First, you must create a relationship between the fact table and the date dimension.

Next, create the above measures in the file.

Here is my test file for your reference.
