Change access control

Change Management utilizes the new Process Designer security controls to permit authorized users to create, modify, and close changes and change tasks. The system provides Update authorization options for Never, Always, When Assigned and When assigned to workgroup. For example, one user may be able to create and close changes or tasks but only modify changes assigned to them.

The system provides the construct of a user role which allows administration of many users with a single role definition.

Access to functionality within each module is governed by HPE Service Manager security utilities, which define access based on role and user.

Service Manager provides a security control to segment data between multiple customers. The Mandantan controls identify which customer data a particular user or group can access, update, or both.
