Installed Configuration Maintenance
Installed Configuration Maintenance (11.3.5) can be used to create and maintain product structures in the installed base. Parent-component relationships can be created directly with this function, or modifications can be made to product structures created in other parts of the system.
Each installed item within the configuration can have a contract or warranty established for it separately. There are several advantages to having the product configuration in the installed base:
Customer service can determine exactly what is in the configuration.
If the item is moved to a different end user, the entire configuration can be moved.
If one or more components are replaced during a service activity, just those components can be updated in the installed base.
