You can use multiple incoming and outgoing links for a workstep without using an intermediary Or-Join, AND or Decision. In addition, Business Process Modeler supports multiple outgoing links for Start worksteps; and multiple incoming links for Decisions and End worksteps.
The following restrictions apply to workstep connections:
You cannot have more than one link of the same type with the same source and target worksteps.
A link cannot originate from and terminate at the same workstep.
The Or-Join and XOR-Join gateways can have only one outgoing link. When an AND Gateway has multiple incoming links, it acts as an And-Join and can have only one outgoing link.
Note: Even though you can now design a business process without using the Or-Join or Decision gateways, these worksteps are still available for users who want to add them to processes to clarify or highlight areas of the process’s workflow.
You cannot have more than one link of the same type with the same source and target worksteps.
