You cannot simultaneously view multiple versions of composite objects, such as mappings and mapplets.

Older versions of composite objects might not include the child objects that were used when the composite object was checked in. If you open a composite object that includes a child object version that is purged from the repository, the preceding version of the child object appears in the workspace as part of the composite object. For example, you want to view version 5 of a mapping that originally included version 3 of a source definition, but version 3 of the source definition is purged from the repository. When you view version 5 of the mapping, version 2 of the source definition appears as part of the mapping.

Shortcut objects are not updated when you modify the objects they reference. When you open a shortcut object, you view the same version of the object that the shortcut originally referenced, even if subsequent versions exist.
