You can create Workflows which are very simple and linear, or you can create Workflows with very fluid decision routing using one or more conditional process Nodes. Recognizable by their flowchart diamond shape in the Designer, the conditional process Nodes are used for TRUE/FALSE logic decisions about documents in a Workflow.
While creating or editing a Workflow with a conditional process Node, the Node path does not have to be set when it is dragged onto the Design Canvas. Only when the Node is linked to another node by dragging a Connection does a second settings dialog box appear. There you must determine the document’s path by making a decision about the next action taken against the document. The Workflow cannot be run without specifying both conditions.
