A Reference Replication configuration defines how to replicate (copy) objects being referenced by or referencing an (source) object. The configuration itself is done on the relational data between two Instance Replication objects related via Reference Replication relation.
The mechanism provides the possibility to configure and control the detailed replication behavior as:
Configuration
Forward Reference
Forward reference means that the source object carries the property refering to a child. It is necessary to configure the name of the reference property. Once the source object gets replicated, the referenced child will be replicated as well based on the configuration of the used reference replication configuration.
 | If you want the new replicated instance to refer to the same child as its source, you have to configure a simple property replication but must not use a reference replication! |
Reverse Reference
reverse reference means that there are one or more children objects carriing the property refering to a source. It is necessary to configure the name of the reference property. Once the source object gets replicated, every single child refering to it will be replicated as well based on the configuration of the used reference replication configuration.
 | For evaluation of reverse references the target Metaclass of the instance replication is used. Make sure that the referenced type carries the reference property! |
