About Complex Join Expressions
In a business process model, you can merge, or join, two or more inputs in a single step, and select from available Boolean logic definitions to define the behavior of the join step. In BPMN models, a join is typically accomplished with a gateway step. Software AG Designer supports both step joins and gateway steps. For more information about gateway steps, see About Gateways and About Gateway Types.
The available join types are:
*OR. The step processes the incoming data when any incoming transition is satisfied (that is, provides data). The OR join is available as:
*A standard OR join, also known as a synchronized OR. This is the default behavior for Process Engine version 8.0 and later.
*An unsynchronized OR, provided for compatibility with Process Engine version 7.x.
For more information, see About OR Join Behavior (Synchronized vs. Unsynchronized).
*AND. The step processes the incoming data only when all incoming transitions are satisfied (that is, provide data).
*COMPLEX. The step processes the incoming data according to the custom join logic you create with a join condition editor.
You can optionally specify a join timeout value. For more information about join timeout behavior, see About Process and Step Timeouts.
