Creating a Parallel Transition

To create a parallel transition, you need to use Parallel Gateway: Unconditionally split/join flows to link one activity to two or more activities. To do this:

Procedure

  1. Create an activity ProductApproved and create three workitem notification activities.
  2. Next, select Parallel Gateway: Unconditionally split/join flows in the Palette.
    • Place it between the ProductApproved activity and one of the workitem notification activities (this represents the split for the parallel transition).
  3. Use the sequence flow to link the gateway with the other Workflow Notification tasks.
  4. Create another Parallel Gateway (Join) sequentially after the Workflow Notification tasks and use the Sequence flow to connect each of the Workflow Notification tasks with it - this represents the point where the three parallel transitions join into a single thread. You can now connect that gateway to another activity and continue defining your process.

Result

Note: Since split and join both use the same Parallel gateway (and since a Parallel gateway can be either a split or join), the application distinguishes a split from a join in the following manner: if there is a single FromActivity for a given Parallel Gateway, it is considered a split, if there is more than one FromActivity, it is considered a join.
