Procedure documentationCreating and Editing an Exclusive Choice Gateway Locate this document in the navigation structure

 

An exclusive choice gateway is a step within a rule flow and has at least two named branches, one of these being a default one. Each named branch has a condition associated with it. If the named branch is default then the condition associated will not be evaluated. It can optionally have actions and local definitions as in rule scripts so as to assist complex computations if required. It is not a reusable entity in Flow Ruleset.

You create an exclusive choice gateway to define a condition or a decision branch in a rule flow.
