Managing Service Effectivity
You can manage service effectivity for the components in a structure, by creating service effectivity objects and associating them to an item. Service effectivity objects can also be created, edited, or deleted for multiple items in an information structure or publication structure. For more information on managing service effectivity for multiple items in a structure, see Adding Service Effectivity to Multiple Items, Editing Service Effectivity of Multiple Items, and Deleting Service Effectivity of Multiple Items.
Service effectivity objects can be created as softtypes to allow the addition of custom attributes. As a default they can apply the following criteria:
• Serial Number
• Date
• Serial Number and Date
Refer to Customizing Service Effectivity for information on registering custom attributes for service effectivity objects.
You can filter a structure based on the service effectivity values of its components. Refer to Filtering on Service Effectivity for further information.
