Explain what Reference Fields are used for within Auditor and if they are audited.
Reference Fields are additional pieces of information that you could see for each audit to help identify, or provide more information about, the record being audited. These Reference Fields will also be seen in the Audit Log. All Primary Keys in a table are automatically marked as Reference Fields.
If you want to see these Reference Fields on an audit record, you must mark the check box on the field in the reference column.
