3.5.1 About Terminal Nodes
A node that represents the start or end of a procedure is called a Terminal Node. Whether Terminal Nodes are displayed in the Operational Content Execution Window depends on the environment. To confirm whether Terminal Nodes are displayed in the execution environment, contact the system administrator.
Note that a Terminal Node at the start of a procedure is optional. In an environment where plugins are not used, the end terminal might also be optional depending on the settings specified during system construction.
