Closed AND rule

Several parallel branches of a process converge in a joining AND rule. The various branches start with a splitting AND rule and converge again with a joining AND rule.

Splitting and joining AND rule

This type of pattern is mapped to one splitting and one joining AND gateway in BPMN.

Branches that only contain events are grouped together in a single branch in the BPMN diagram. The conditions are combined in such a way that each condition generates a separate line in the Condition expression attribute of the connection.

The graphic displays an example with two branches, but any number of branches can be modeled.
