Subprocess management

Learn how to configure, start, and execute subprocesses efficiently within your process flow.

Subprocesses are smaller process flows triggered by actions in the main process. They can inherit some process parameter values from the parent process and communicate with front-end apps using the same connection details as their parent process.

Overview

Subprocesses can be started in two modes:

• Asynchronous: Execute alongside the parent process without delaying it.
• Synchronous: The parent process waits until subprocesses are finished before advancing.

Configuring & starting subprocesses

Design subprocesses within the FlowX Designer, mirroring the main process structure.

1. Start Subprocess Action

   • Within user tasks or task nodes.
2. Call Activity node

   • Custom node type in the main process.
3. Start Embedded Subprocess node

   • Using the corresponding node.

Parameter inheritance

Available for Start Subprocess action and Call Activity node.

By default, subprocesses inherit all parent process parameter values. Configure inheritance by:

• Copy from Current State: Select keys to copy.
• Exclude from Current State: Specify keys to ignore.

Sub-processes can also have an Append Params to Parent Process action configured inside their process definitions which will append their results to the parent process parameter values.

Append Params to Parent Process

Executing subprocesses

Define subprocess execution mode:

• Asynchronous/Synchronous: Set the startedAsync parameter accordingly.

In synchronous mode, subprocesses notify completion to the parent process. The parent process then resumes its flow and handles subprocess data.
