Use

PCD content is organized into units, which are semantic objects (such as iView, page and role) whose parent hierarchy consists only of plain folders. A unit includes the semantic object's complete child hierarchy, and the semantic object is called the root of the unit.

For example, a page in a folder in the top-level Portal Content folder is a unit, but an iView in the page or a delta link of the page in a role are not units.

Many tasks can only be performed on units and not on objects within a unit. The following features apply only to unit objects:

  • Permissions: Only unit objects and plain folders have access control lists (ACLs). Objects inside a unit object inherit their ACLs from the unit object.

  • Delta Links: Delta links can only be created from unit objects.

  • Transport: Only unit objects can be transported.

  • Translation: Translation worklists include only unit objects.

  • Caching: Only unit objects can be cached.

Unit Attributes

Unit attributes are stored on a unit, and include attributes such as:

  • CREATED_AT

  • CREATED_BY

  • LAST_CHANGED_AT

  • LAST_CHANGED_BY

  • ORIGINAL_LOCALE

Unit attributes are identified by their namespace: com.sap.portal.pcd.unit .

For more information about unit attributes, see the IUnit interface in the Javadocs at http://help.sap.com/javadocs.
