Popup window when hovering over a reference icon shows a different form section than the top form section.
The reason the popup is not displaying as expected is because there are no sys_popup views configured for the referenced table. When the system tries to access this view and there is not one to use, it can cause unpredictable results, like displaying a random form section.
For example, if you are on the Incident form and hover over the reference icon near the populated Assigned To field, if there is no sys_popup view defined for the sys_user table, an unexpected form section might be displayed.
This can be fixed in any instance by the following steps:
1. Navigate to- https://<instance_name>.service-now.com/<table_name>.do?sysparm_view=sys_popup
This will show a form even if one does not yet exist, it will pull fields from the default view.
2. Right Click the header and choose Configure → Form Layout
3. Users can click save to create the view as it looks now, or they can modify the fields/form sections displayed by customizing it to their needs and clicking save.
4. There should now be a sys_popup view for this table which will be visible upon hover of the reference icon.
