In Both cases the request ends but in first scenario, it is positive completion achieving the end process goal and in the second step its negative completion. Also note how the actions work. Changing deployed process definitions Injecting resources programmatically 7. Parsing an xml String Expressions in mails If you notice it has a child element called Transition which means that the output of the start workstep is going to go as in input to the HOD workstep.
A process has to have at least one start activity. The super process execution will then take outgoing transition ok to next step. Suppose that wiring the money and archiving can be done in parallel.
