You can add a subprocess to a process in a stage to call an existing flow in your application. By using subprocesses, you can compartmentalize functionality and simplify the presentation of a process in a case type.
By default, subprocesses run in the context of the current case. You can change the context if your subprocess needs to update a specific case or class.
In the Explorer panel, click Cases, and then click the case type that you want to open.
On the Workflow tab, click Life cycle.
Hover over a process in a stage, and then click + Step > More > Processes to display a list of flows.
To change which flows are displayed in this list, use the Relevant Records tab on the Application Inventory landing page.
Click the name of a flow to review the flow description.
Click Select to add a subprocess to the life cycle that calls the flow.
If the flow accepts parameters, pass values for those parameters by entering values in the Parameters section of the contextual property panel.
Click Save.
