3.1.3 Creating flow hierarchies
A flow hierarchy is created when you define a flow within another flow. You can define a maximum of 25 hierarchical levels, with the top-level flow being level 1.
You can create a flow hierarchy by deploying flow plug-ins, and repeat a unit of processing that consists of several steps by deploying repeated-execution plug-ins.

Hierarchical step |
Created a flow hierarchy. |
|
Repeated-execution plug-in |
Repeated step |
The system repeats execution of the specified flow. However, if you want to impose a hierarchy on a flow subordinate to the repeated step, you must use a flow plug-in. You cannot place a repeated-execution plug-in in a flow that is subordinate to a repeated step. Also, if you attempt to impose a hierarchy on a flow you have copied and pasted that includes a repeated step, an error occurs. |

Other plug-ins |
Ordinary step |
The system executes the plug-in. |
When you execute a service template that includes a hierarchical flow, only the top-level steps in the flow appear in the Task Details dialog box. Steps in subordinate flows and in flow plug-ins and repeated-execution plug-ins are not displayed.
- Tip
-
You can view a list of the steps in a flow in the Flow Tree view on the right side of the Editor window. In the Flow Tree view, the name of the service template appears as the first step of the flow. Lower levels are represented by the step name associated with the step that executes the flow plug-in or repeated-execution plug-in.
