Null

Activity

The Null activity is an activity with no action performed. This activity has a name and a description specified on the Configuration tab, but there is no input or output for the activity.

This activity is useful if you want to join multiple process flows. That is, when you have multiple transitions out of an activity and each transition takes a different path in the process definition, you can create a transition from the activity at the end of each path to a Null activity to resume a single flow of execution in the process.
