Run Sub Flow

Run Sub Flow

Overview and Key Concepts

The Run Sub Flow activity can be used to initiate a sub process flow. The entering token will remain in the Run Sub Flow activity until all of its child tokens have completed their sub flow (by exiting a Finish activity).

Consider reading Sub Process Flows for more in-depth information.

When this activity is first created, a red exclamation mark shows up to the right of the activity. This is notifying you that a link to the Run Sub Flow activity is required. This can be either to a Process Flow Sub Flow object that has a Start activity in it or to a Start activity in the same process flow. This link may be a direct pointer which can be created by clicking on the exclamation mark and then clicking on a Sub Flow object or Start activity, or the reference may be dynamic by setting the value for the Destination property.

Starting and Finishing a Sub Flow

The Run Sub Flow activity requires a Start activity as the first activity in the sub flow and a Finish activity as the final activity. As child tokens enter the Finish activity, they notify the parent token (in the Run Sub Flow) that the child is complete. Once all children have completed the sub flow, the parent token will be released from the Run Sub Flow.

If the Run Sub Flow references a Process Flow Sub Flow object, it will search the Sub Flow for the first Start activity and use that as the start of the sub flow. If your Sub Flow has multiple Start activities, you can use the Sampler to a specific Start activity or enter SubFlowName: StartName in the Destination box.

Connectors

The Run Sub Flow activity only allows one connector out. See Adding and Connecting Activities for more information.
