The object store Version view site preferences determine the version properties displayed in your client application:
A user can display a list of versions for a selected document. After selecting a specific version, the user sees that version's properties. The Document Name preference identifies the first column of the version properties.
With the Version view preference, you can select up to six properties to display.
NOTE If a document belongs to a document class that does not include the property selected in the Document Name preference, the first field of the Version view shows "Not defined." For best results, use a system property (identified by an asterisk (*) in the drop-down list) or a property that is included in all document classes.
