Howdy team, this is my first post to Thwack. I am not a programmer and I am new to SW. We are installing NPM 12.0.
I am trying to create a group that tracks certain custom property fields which are "Empty". The purpose of this is to identify new devices without proper information easily and efficiently. It is must more efficient in SQL to do a search for a MATCH, verses DOES NOT MATCH.
I created a Custom Property called "Region" that is
1. Test
2. Required Property
3. drop-down list

Background: I have some Nodes without this Property filled in. However, I can't perform a search for the nodes that do not have the field filled out. Below is an attempt to create a build a Group with the Region field blank. We will have several thousand nodes, and I want my searches to be efficient for SQL.

Is there a way to search for a custom property that is empty?
