PREVIOUSQUARTER returns nothing

Hello, this really has me stumped as everything else works OK! I can count and average if I put in manually the dates and the current quarter time intellignce works but not the previous quarter ones....

I also downloaded the file, and to expand on the previous comment, PREVIOUSQUARTER finds the earliest single date visible in the current filter context, then returns the quarter previous to it.  In this case since you don't select a date the earliest visible is the first date in the 'Date' table and therefore can't go back any more.  So PREVIOUSQUARTER returns blank, which causes the CALCULATE to return blank.

Thanks, that makes sense. So what good is previous quarter? Can I feed a context from as the current date to the previous quarter or just find a different way to do this without previousquarter. Quarters are a little harder than years and months because quarters may "overlap" years.

    I usually prefer to put slicers on the page for Year/Quarter/Month so people can interact with report, but you can do this:  

     

    Response Prev Q Avg = 
var _today = FILTER( VALUES( 'Date'[Date] ), 'Date'[Date] = TODAY() )
RETURN
CALCULATE ( AVERAGE(system[ResponseTime]), PREVIOUSQUARTER( _today ) )
