    Hi,

     

    hope this will help you. Dynamic measure based on your calendar.

    Count Correct Rows =
    var date_ref = SELECTEDVALUE(dim_calendar[Date])
    return
        COUNTX(
            FILTER('Sample';AND('Sample'[Status Start Date] <= date_ref;'Sample'[Status End Date]>=date_ref));
            COUNTROWS('Sample')
        )
     
    You can use Program column as you want. No relationship needed.

Hi bolfri ,

 

This Solution does exactly as expected.  Thank you!

 

One follow-up question.  I'd like to show date hierarchy on my axis, with date rolling up to Month & Quarter.  PBI will not accept the Month or Quarter axis - visual shows blank when I try that.  Is there a way to rewrite this to account for those?  Can they be included as variables?

 

Thanks again!

Sure. I needed to change it a little, but this i a result:

Count Correct Rows - Aggregatable =
var min_date = FIRSTDATE(dim_calendar[Date])
var max_date = LASTDATE(dim_calendar[Date])

return
    COUNTX(
        FILTER('Sample';
            AND(
                OR(
                    OR(
                        //Scenario 1
                        AND('Sample'[Status Start Date]<=min_date;'Sample'[Status End Date]>=max_date);
                        //Scenario 2
                        AND('Sample'[Status Start Date]>=min_date;'Sample'[Status End Date]<=max_date)
                    );
                    OR(
                        //Scenario 3
                        AND('Sample'[Status Start Date]<=min_date;AND('Sample'[Status End Date]>=min_date;'Sample'[Status End Date]<=max_date));
                        //Scenario 4
                        AND(AND('Sample'[Status Start Date]>=min_date;'Sample'[Status Start Date]<=max_date);'Sample'[Status End Date]>=max_date)
                    )
                );
            //Exclude all records with wrong data, when start is after end
            'Sample'[Status Start Date] <= 'Sample'[Status End Date]
            )
        );
        COUNTROWS('Sample')
    )
 
Graphic representation on each scenario:

 

Result:
Count Correct Rows - Aggregatable - new one

Count Correct Rows - old one, that works only for day representation
