Note: The 
Reuse Process command is intended to provide a
                        quick means for creating shortcuts to processes in your Process Hierarchy
                        Diagram, primarily when working with the Analysis language, and is not
                        available in other BPM diagrams. For some languages it is hidden completely.
                        If you are working with BPMN or an execution language, it may be more
                        appropriate to set the implementation type of the process reusing another
                        process to 
Reuse process or 
Execute
                            operation (see
Implementing Processes).
