- Workflow definition
  A workflow is a set of tasks to be run, together with times, priorities, and other dependencies that define the processing order.
- 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.
- Event source definition
  An event source is an item that allows HCL Universal Orchestrator to receive events from specific event plug-ins.
- Calendar definition
  Calendars define the days in which workflows do or do not run.
- Folder definition
  You can use folders to organize your items accordingly to your business needs.
- Credentials definition
  Credential definitions are used to store user IDs and passwords, or tokens.
- Variable table definition
  Variables are values that can change according to the purpose of workflows and task templates.
- Workstation definition
  A workstation is a scheduling item that runs tasks.
- Event plug-in structure
- Managing matching criteria
  In this topic you can find a description of matching criteria.

      This topic shows how to pass properties from one task integration to another task in the same workflow instance.
    - Passing variables set by using jobprop in one task to another in the same workflow instance
      You can use the jobprop utility installed on HCL Workload Automation dynamic agent to set one or more variables and their value in a task and pass it to the successive task in the same workflow instance. This utility is supported only on executable tasks.

Passing variables between tasks

This topic shows how to pass variables between tasks.

In many scenarios, the task output or a task property of a task in a workflow can be the input for the execution of a successive task in the same workflow or in a different workflow.

In the following scenario, you have TaskA and TaskB in the same workflow instance and TaskA is a predecessor of TaskB. TaskA passes some properties to TaskB at execution time.

You can pass the following properties from TaskA to TaskB:

TaskA exports some properties and TaskB references these properties in its definition as variables in a predefined format. At execution time, variables in TaskB are automatically resolved. The task properties that you can export depend on the task type you are defining. See Passing properties from one task integration to another task in the same workflow instance.
Only for executable task. TaskA sets some custom property values by using the jobprop utility on HCL Workload Automation dynamic agent. TaskB references these properties as variables in its definition. At execution time, variables in TaskB are automatically resolved. See Passing variables set by using jobprop in one task to another in the same workflow instance.
