CN Relationships
Change Orders contain one ore more Change Activities. Each Change Activity can contain zero or more Changeable objects, each reflecting a changed business object. Changeable objects can be of the following types (see the figure CN Structure below):
• Part (separable, component)
• Part (BOM or assembly)
• Co-produce Part (BOM or assembly)
• Process Plan
• Sequence (via association with a process plan)
• Operation (via association with a process plan)
• Tooling
• Process Material
• Skill
• Document (includes both WTDocuments and CAD documents that are either standalone objects or in association with a part, a process plan, a sequence, an operation or a resource)
• CAD document structure
• OptionSet (When ESI Options and Variants is installed)
• ChoiceRule (Only local choice rules and when ESI Options and Variants is installed)
The figure above illustrates the relationship between Changeable2 and ChangeActivity2. A Change Activity can have zero or more Changeables. Each Changeable can be associated with zero or more Change Activities.
There are two associations between Changeable2 and ChangeActivity2. The first association is represented by AffectedActivityData, and associates a Change Activity with a business object to be changed as part of the change activity. The second association is represented by ChangeRecord2, and associates a Change Activity with the business object changed as part of the change activity. The former links the business object before the change, and the latter links the business object after the change.
