Links connect schema elements and define the logical flow of the workflow from one element to the next.

Elements can usually set only one outgoing link to another element in the workflow and one exception link to an element that defines its exception behavior. The outgoing link defines the standard path of the workflow. The exception link defines the exception path of the workflow. In most cases, a single schema element can receive incoming standard path links from multiple elements.

The following elements are exceptions to the preceding statements.

  • The Start Workflow element cannot receive incoming links and has no exception link.

  • Exception elements can receive multiple incoming exception links, and have no outgoing or exception links.

  • Decision elements have two outgoing links that define the paths the workflow takes depending on the decision's true or false result. Decisions have no exception link.

  • End Workflow elements cannot have outgoing links or exception links.
