For Enterprise Resource Planning (ERP) systems such as SAP R/3 or IBM SanFrancisco, the tailoring of reference models for customizing the ERP systems to specific organizational contexts is an established approach.In this paper, we present a methodology that uses such reference models as a starting point for a top-down integration of enterprise applications.The re-engineered models of legacy systems are individually linked via cross-mapping specifications to the forward-engineered reference model's specification.The actual linking of reference and legacy models is done with a methodology for connecting (new) business objects with (old) legacy systems.
