About Completion Events
Completion events are used to implement the outcome of an activity. They are created by either the communication out (for one-way communication) or the communication in (for two-way communication). Completion events are executed by the activity orchestrating the communication with the external system.
Some examples of the tasks a completion event will perform are:
Commissioning, decommissioning, connecting, disconnecting a smart meter
Installing or Removing a meter or item
Creating initial measurement data
Updating a device or service point
