Calculated measure to select only 'non-empty' values

This seems so simple yet I cannot figure it out.

If I add a field to my Page Filter list, I can easily set the dropdown to select only records where the field is empty; I can search and bookmark for (none).

However, I would like the opposite scenario. I want the dropdown to allow selection of only ‘non-empty’ records. I can create a calculated member but I cannot get the syntax correct. Do I use NOT IsEmpty()? This is just a freeform text field but I want to exclude records where the field is NOT populated.

Tried to use the page filter (have to select the wanted field first from your measures)? → filter rows → not matches (none)

This is not providing the desired results. Records with “(none)” are still being included. There has to be a syntax / formula that can be used in a Calculated Measure to only retrieve “non-empty” records??

Ultimately I am trying to get a view of Total Issues Created / Resolved each month, but only want issues where the “Service Ticket” field has values in it (non-empty) included in the total created/resolved calculations.

This current view includes all issues and not the desired filter. For instance, November has 74 Issues Created; I want to exclude out of the 74 any issues where Service Ticket is (none).

Try this, make the same calculated for issues resolved then.

Count(
Filter(
–iterate through linked members
Descendants([Issue].CurrentMember, [Issue].[Issue]),
NOT ([Service Tickets].[Issue created]) MATCHES “(none)”
)
)

Thanks for the suggestion. I have not tried it as I found an alternate approach. I created a new calculated field at Import which is populated with “Y” if the Service Ticket field is populated. I then use this new field to filter in the records I want to include in the report. This is working well.
