Defines expressions that determine the relationships and directions used to populate the list of files for quick file access. If a table or structure browser contains a column type of File (displays the icon)
and does not provide a relationship filter, this property defines the relationship to use to locate files
checked into objects connected to the object. If the table or structure browser column definition
includes a relationship filter, this property is not used. Use symbolic names for all relationships. For example: from[relationship_ReferenceDocument].to.id,
to[relationship_ReferenceDocument].from.id |
