Connection to
the Document Flow 
In the application system, business objects (documents) have a hierarchical relationship to one another. For example, a sales order consists of multiple deliveries that in turn fulfill multiple shipments. The connection to the document flow enables SAP Event Management (SAP EM) to display this hierarchical structure of the business objects in the Web interface.
