Responsibility for Maintaining Service Instances
The access rights that the Configuration Manager role offered for registering and updating service instances has been transferred to the Service Level Manager role. Several 4me customers requested this adjustment and their reasoning seems sound.
These organizations give many of their specialists the ability to maintain the CMDB, but they want to limit the ability to maintain the service instances to just a few people; specifically the people who manage the services, service offerings and SLAs.
Note that configuration managers can still place a service instance record in Edit mode to add or remove configuration items. An overview of all the roles and the access rights they provide can be found in the online help.
