Process fragments are pre-defined, reusable fragments of a process definition that can be added to process definitions. You can use process fragments to quickly define processes.
Process fragments are displayed as part of the Navigator view. When a new process fragment is created it appears as a Business Process Fragment (.bpf) file in the Process Fragments project folder in the Navigator view. When you open a process fragment it is displayed in the Process Definition editor. You can add/remove nodes and arrows in this editor
