How to Add Request Offerings to Service Offerings
In System Center 2012 – Service Manager, service offerings are logical groups of request offerings. For a service offering to appear in the Self-Service Portal, each service offering must have at least one request offering added to it. After a service offering and a request offering are published, it is a straightforward process to associate them as a collection.
