The Work Management module of SAP IS-U manages work for engineers for replacing, inspecting, and installing meters/devices. It manages objects such as Service Orders and Service Notifications.
Service orders represent a piece of work that must be carried out. Via the service order itself, the process of initiation through to implementation can be tracked. An open service order or one in an error state can high-light to the user that some task has yet to be carried out.
The Service notification is for planned or unplanned work. From a service notification a service order can be generated. An open service notification or one in an error state can high-light to the user that some piece of planned/unplanned work has yet to be carried out.
