Selecting the reference (i) icon in Service Portal shows error "No elements to display"

All supported

This issue could be due to one of the following: 

1. The default view has a field of type Field Name. This issue is a problem (PRB) that is fixed in the Madrid release.
2. There is a corrupted field on the view. Specifically, one of the columns in the view had an incorrect value for table reference in the dictionary.

To fix the issue, do one of the following:

1. Review the fields in the default view of the table being referenced and make sure there is no field type, Field Name. If you are already using the Madrid release, follow solution 2.
2. Start removing fields from the default view on the affected table until you find the one causing issues, and then open the dictionary entry for that column and review its configuration. Open a case with Support if you are unable to find what is wrong.
