Some objects in a mapping are also stored as independent objects in the repository:
Sources
Targets
Reusable transformations
Mapplets
The mapping is dependent on these objects. When this metadata changes, the Designer and other
CDI-PC Client
applications track the effects of these changes on mappings. In these cases, you may find that mappings become invalid even though you do not edit the mapping. When a mapping becomes invalid, the Integration Service cannot run it properly, and the Workflow Manager invalidates the session.
The only objects in a mapping that are not stored as independent repository objects are the non-reusable transformations that you build within the mapping. These non-reusable transformations are stored within the mapping only.
