The Owned by relation denotes a parent-child relationship. The primary key(s) of the owning file become part of the primary key of the owned by file. For instance, if Order Detail is Owned by Order, the key of Order, Order code, is the high order key of Order Detail.
The file of an Owned by relation must be of type REF or CPT. All the key fields of the owning file are incorporated as high order keys in the owned file.
A file can have more than one Owned by relation. A file can have only Owned by relations to define its keys. It is not necessary to have other key relations, such as Known by or Qualified by.
The Owned by relation allows you access to any of the fields on the owning file. If a field is accessed on the owning file, it creates a virtual field on the owned file. Virtual field values can be used but cannot be updated.
An Owned by relation can have its description clarified by using the For text extension.
See the section Using for Text and Sharing with Relations for more information on using text and Sharing with Owned by relations.
