Calculating a value based on current and previous month

[Anonymous]

I have a measure which counts how many passes and fails there are in a dataset called 'Loaders&Assessors Results' in a column called [Result]

The audit date is in a table called 'Loaders&Assessors' and is called [Date Audited]

The fail measure in its current form is

Fail = CALCULATE(COUNTA('Loaders&Assessors Results'[Result]),FILTER('Loaders&Assessors Results','Loaders&Assessors Results'[Result]="Fail"))

I would like to add two additional measures, for current and previous month. I tried myself and failed.

First make sure you have a relationship established between 'Loaders&Assessors' and 'Loaders&Assessors Results',  then try this:

Previous Month Fail = CALCULATE(COUNTA('Loaders&Assessors Results'[Result]),FILTER('Loaders&Assessors Results','Loaders&Assessors Results'[Result]="Fail"), PREVIOUSMONTH('Loaders&Assessors'[Date Audited]))

Current Month Fail = CALCULATE(COUNTA('Loaders&Assessors Results'[Result]),FILTER('Loaders&Assessors Results','Loaders&Assessors Results'[Result]="Fail"), DATESBETWEEN('Loaders&Assessors'[Date Audited],DATE(YEAR(TODAY()),MONTH(TODAY()),1),ENDOFMONTH(DATE(YEAR(TODAY()),MONTH(TODAY()),1))))

Hi and thanks @Anonymous 

The measures don't quite work, I had tried the exact same previousmonth measure as you, and it returns no value although I can't see what the issue is!

The current month measure errored, I have played around with it and it seems the below is pulling through the correct number:

Current Month Fail = CALCULATE(COUNTA('Loaders&Assessors Results'[Result]),FILTER('Loaders&Assessors Results','Loaders&Assessors Results'[Result]="Fail"), DATESBETWEEN('Loaders&Assessors'[Date Audited],DATE(YEAR(TODAY()),MONTH(TODAY()),1),ENDOFMONTH('Loaders&Assessors'[Date Audited])))

If you can think of a reason why the previousmonth measure it's pulling through a number, let me know!

Hi @Anonymous 

I have tested this one in one of my datasets and it worked, give it a try:

Previous Month Fail = CALCULATE(COUNTA('Loaders&Assessors Results'[Result]),FILTER('Loaders&Assessors Results','Loaders&Assessors Results'[Result]="Fail"),DATESBETWEEN('Loaders&Assessors'[Date Audited],DATE(YEAR(TODAY()),MONTH(TODAY())-1,01),DATE(YEAR(TODAY()),MONTH(TODAY()),01)-1))

Hope it helps!
