I would like to see a filter set up in NXT analyze so that I can get rid of donors who have a SSN on their record - that's how we track employees. It would be nice to filter on that so that it just shows those people and also be able to remove them from other retention reports.
We also use SSN for our college ID (students & staff). We prefer this field b/c it is one of the fields allowed for import and because it only allows a unique entry per constituent, it flags us if we try to enter a constituent who's ID is already in the system. Our IDs stay with students even if they become staff, so it's a wonderful way to confirm that a person is the same and is not a duplicate. Losing this functionality in the move to webview would not be ideal.
Many of my clients use this field for importing staff payroll gifts, and other imports - ability to search, filter on or out, and see in web view is important!
