Interactive Filter for External ID string field (Empty / Not Empty) on Dashboard

[ssaanvi]

Hi Everyone,

I have a requirement to add an Interactive Filter on a dashboard for the External ID field.

The requirement is to provide users with only two filter options:

• Empty – Displays only Incident records where External ID is empty.

• Not Empty – Displays only Incident records where External ID is not empty.

When a user selects one of these options, all reports on the dashboard should be filtered accordingly.

I tried implementing this using the standard Interactive Filter approach and followed the ServiceNow documentation, but I'm not getting the expected results. 

Has anyone implemented a similar requirement?

• Is this possible using an out-of-the-box Interactive Filter?

• If a custom solution is needed, could you please share an example or point me to the right approach?

Create a Core UI filter to tell if a field is populated • Australia Platform Analytics • Docs | Serv...

Any guidance or suggestions would be greatly appreciated.

Thank you!
