You build a workflow by creating a sequence of schema elements that define the logical flow of the workflow.
By default, all elements in the workflow schema are linked. Links between the elements are represented as arrows. When you add a new element to the workflow schema, you must drag it onto an arrow or an existing workflow element that is not linked to a next element. After you add workflow elements to the schema, you can delete existing links and create new links to define the logical flow of the workflow.
You can copy an element or a selection of elements from the schema of an existing workflow to the schema of the workflow that you are editing. See Copy Workflow Schema Elements.
A workflow schema must have at least one End workflow element, but it can have several.
