Architecture of SAP ERP

Inside SAP ERP, SAP R/3 enterprise was just a component. As you can see here, from this point on SAP ERP was more than just SAP R/3 Enterprise with SAP NetWeaver, since it offers many functional enhancements like Self Services, self service procurement, internet sales, and SAP SEM. SAP Net Weaver also contains the SAP Web Application Server. With SAP ERP, a new SAP solution was born. The SAP ERP Central Component or SAP ECC, is the evolutionary successor of the previously offered SAP R/3 Enterprise, and is the central core of SAP ERP. Compared to the SAP R/3 Enterprise, in SAP ECC there are architectural changes with respect to Enterprise Services Architecture, enhanced usability and new developed functionality, like the new general ledger. SAP Business Warehouse, SAP Strategic Enterprise Management, and Internet Transaction Server integrated into SAP ECC. Customers now have the option to run these components on the same instance that runs SAP ECC to reduce the system landscape and save costs. Running the components on separate instances is also possible. SAP Web Application Server contains all capabilities of SAP basis as well as additional web capabilities.
