Hello lbendlin ,

 

Thanks for your thought, I understand what you are saying.

 

Let's do it this way:

 

I have a formula that calculates the resolved tickets.

total_tickets_solved = 
COUNTROWS(
    FILTER(
        tickets,
        RELATED('status'[description]) = "Completed"
    )
)

This formula works smoothly as you can see.

 

Now my next step is to calculate the number of solved tickets for the previous month. So adding the metric that already works and invoking the previous month function, the formula would be this:

tmp = 
CALCULATE(
    [total_tickets_solved],
    PREVIOUSMONTH('calendar'[date])
)

 

But it does not work, the result returns blank.

So in my understanding this means that the problem is in the relationship between the ticket table and the calendar table.

 

Any suggestions to confirm what I think?

 

Thanks for any comments.

Hi ajdm2007 ,

 

Have you done any filtering on the calendar date column?

 

You referenced the calendar date column in the PREVIOUSMONTH function.

 

If not, the PREVIOUSMONTH function returns all dates in the previous month using the first date in the calendar date column as input. However, this returns the empty table.
This causes the card visual to return blank.


You can try adding the calendar date column to the slicer, select a date and see if the card visual changes.

 

Best Regards,

Dengliang Li

    Hello Anonymous ,

     

    Thanks for your input! I do have filters enabled, and there's data in the ticket table as well.

     

    I’m pretty sure the issue is with the calendar table, which is related to the tickets table (calendar - DATE field / tickets - DATEONLY field).

     

    I’m not sure what I might be doing wrong or if there’s an issue with the table, but there are no filters applied to it.

     

    Thank you for any other advise.

     

    Have a good one,
