Welcome
Orchestrating
Orchestrate anything with HCL Universal Orchestrator.
Task definition
A task definition is a unit of work that specifies an action to be performed on specific workstations in the HCL Universal Orchestrator network.
Subflow task
The task type that sets or references a valid workflow within a task. It is a workflow that is nested within a task. You can extend the functionality by adding multiple subflow tasks in a workflow, with each task containing a single workflow. The subflow task facilitates simultaneous submission of multiple workflows.
Managing a subflow task from the UI
You can create a subflow task using the UI. Add the mandatory and optional parameters to create a unique subflow task.

What's new
HCL Universal Orchestrator is constantly evolving to offer you the most comprehensive orchestration capabilities. For known limitations, workarounds, and contact information of HCL Customer Support, see Release notes.

Managing a subflow task from the UI

You can create a subflow task using the UI. Add the mandatory and optional parameters to create a unique subflow task.

Before you begin

You must have the USE permission on the workflow that needs to be referenced in the subflow task.

Procedure

Log in to the UI using valid user credentials.
Select the Design tab from the home page.
In the Graphical Designer page, select the Assets tab.
Click the Plus icon.
From the drop-down menu, select Task template.

Select the Subflow plug-in from the Add new task template dialog, and then click Next.

The Add new task template dialog opens. Enter valid details for the mandatory fields. If required, you can also specify the optional fields.

Table 1. Mandatory fields
Options	Description
General information
Folder	Specify a folder to save the task definition. The default value is the root folder (/). The name must start with a letter, and can contain alphanumeric characters, dashes, and underscores. The name of the folder cannot contain spaces. You must include a forward slash (/) before the folder name if you want to define an absolute path, while it is not required for relative paths.
Name	Specify a name for the subflow task. The name must start with a letter, and can contain alphanumeric characters, dashes, and underscores. The name cannot contain spaces.
Workstation	You can specify the name of the workstation and also the name of the folder in which the workstation is defined, if any. The name must start with a letter, and can contain alphanumeric characters, dashes, and underscores. The name cannot contain spaces.
Action
Workflow	Specify a valid workflow key (workstation name with workflow name separated by a number sign (#)) or drag and drop a workflow from the palette.

Table 2. Optional field
Option	Description
General information
Description	If required provide any free text.
Action
Variables	Specify key-value pairs as variables. The values can be a JSONata expression that is resolved while the task is running. Any terms in the subflow task definition that matches the key in the key-value pair is replaced with their corresponding values, effectively resolving the subflow task definition.

Click Add.

Results

You have successfully created a subflow task. You can add the task to any existing or new workflows, and then submit the workflow.
