Linking Relationship Types
When you select a link relationship type when linking products, the system automatically links those components that are specified by the relationship type to be linked.
* 
Relationship types are defined by your administrator.
To link products, select a relationship type that includes the (Linked) indicator. If you select a relationship type that does not include the (Linked) indicator, product options are copied but not linked.
Relationship types that link product options do not necessarily link all product options selected. Some product options are not available for linking. Property settings determine which product options are linked for a given relationship type. In addition, link relationship types selected when linking existing products only link product attributes. They do not link any product options.
Circular Relationship Creation
The system does not support the creation of circular relationships, in which a parent product is also the child of one of its children. If you attempt to create a circular relationship, the system fails to establish the link, and displays a warning message, alerting you that the relationship cannot be created.
Circular relationships also apply to situations where you attempt to link a grandparent to one of its grandchildren. These relationships are not supported, and the system displays the message that the relationship cannot be created.
