Uniques

[UNIQUE_FIELDS = <field>[, <field>]…]

[UNIQUE_RELATIONS = <relation>[, <relation>]…]

The <uniques> definition is optional. It lists the fields and/or relations that form the object's unique key.

The <field> value is a field on the object; it must be specified in the fields section of the import object. The <relation> value is a relation on the object; it must be specified in the relations section of the import object. Either one or both of the <uniques> values can be listed. Note: If both are listed, the UNIQUE_FIELDS must be listed first.

The <uniques> definition can affect the import in different ways:

• If the <uniques> definition is used with an OBJECT, and the fields and/or relations do not match any other database objects, a new object will be inserted.
• If the <uniques> definition is used with a REFERENCE or DELETE, and the fields and/or relations do not match any other database objects, the system will issue an error.
• If no <uniques> definition is entered for an OBJECT, ArchiveManager will first search for <uniques> already defined for the object type in the database index. If no unique fields or relations can be found, the object will be inserted as a new item.
