The PBS (Project Breakdown Structure) Explorer presents database content depending on user needs. It is accessible from the Database group of the Home tab:

The data can be shown as one or more user-defined structures. Each structure is shown in the explorer as a hierarchy starting from a separate root node and can show database items organized according to their to system, class, and so on, as defined in Lexicon (see Project Breakdown Structure in the Lexicon User Guide).
The PBS Explorer tree is generated during runtime from Lexicon definitions. Its nodes can represent database items as well as just label texts generated from the definitions. By selecting a node connected to database item, you can navigate the database hierarchy (set current element). Also, a context menu with basic commands is available for selected nodes.
