It is possible to 'call' a another Workflow inside of a Workflow with the Workflow Unit. This is especially useful to structure your main Workflow and to reduce the (visual) complexity of it. A Workflow which is called via a Workflow Unit can be used like a standard Unit by defining Input and Output Ports (as described in chapter → Published Inputs and Outputs).

Using the Workflow Unit

There are two ways of using the Workflow Unit.

Using the Context Menu

  1. Select In the Workflow View, select the Units you want to put into a separate Workflow.
  2. Right click one of the selected Units and select Create Workflow Unit from selection from the context menu.
  3. You will be asked to give provide a name to the new Workflow.
  4. The Units are moved into a separate Workflow and a Workflow Unit is automatically created and placed into you current Workflow. If there were any connections to the respective Units, the Input and Output Ports are automatically created and connected.

Using the Workflow Unit

  1. Add a new Workflow to your Project.
  2. Add the desired Units to this new Workflow.
  3. Publish Inputs/Outputs (as described in chapter → Published Inputs and Outputs).
  4. Select the Workflow which will call the previously created Workflow.
  5. Add a Workflow Unit to this Workflow.
  6. Select the desired Workflow in the "Workflow" drop-down menu.
  7. Once selected, the Workflow Unit will change its appearance and shows the Inputs/Outputs as well as a preview of the selected Workflow.
