== External reference ==
Such Proxies (its properties) will automatically reference to the instance of the targeted MetaProxy (as given by the underlying Reference) having the same entry in its external Primary Key property than the given Proxy instance. {{Hint|When using external keys and external references it is not of relevant which object is processed first, as the linking will be done either way by the system!}} {{Attention|Only one External Primary Key Property external primary key property is supported for one per MetaProxy object. Hence, the External Primary Key external primary key can consist of only one MetaProxyProperty.}}
