Most Common Types

The following types of correspondence are:

• Non‑shared component object-A non‑shared component expansion object is integral to the scoping object and the scoping object owns it. No other scoping object has an interest in it or can change it in any way. It belongs exclusively to the scoping object it is a component of, even if that scoping object is embedded in another scoping object.

  Examples of non-shared objects are action statements, bilingual text for system default and screen objects, and local or work views.

  If you request Modify protection on a scoping object that has wholly owned subsidiary objects, these non‑shared components are upgraded to Delete protection. For example, an action block with Modify protection gets its action statements with Delete.

• Shared component object-The shared component expansion object is a part of the scoping object, a part of the basic definition of the scoping object.

  For example, system defaults are a part of a business system and, therefore, are shared components.

  

• Shared companion object-The shared companion object is not a part of the scoping object, but some part of the subset requires it.

  For example, the entity types that are used in information views are frequently shared companion objects-if the entity types are specified, or referenced, in earlier stages of view maintenance. These entity types are also named referenced entity types.

  Shared companion objects to a scoped entity type include:

  • All entity types that have relationships with the scoped entity type
  • All entity types that have relationships that are used to identify:
    • The scoped entity type
    • Shared companion entity types
