Summary
• The SAP System Landscape is a server environment comprising development, quality
assurance, and production systems in an ABAP stack.
• Three-System-Landscapes are recommended for SAP ABAP development and config-
uration projects.
• Four-System-Landscapes are recommended for SAP Java development projects.
• The client concept in ABAP systems helps to isolate data environments where parallel
activities can be organized within the same SAP instance.
• Client data can be categorized into client-dependent and client-independent.
• Client-dependent data is accessible within the same client.
• Client-independent data is accessible across all the clients in a SAP instance.
• SAP client instance strategy allows for orderly development and configuration in
ABAP stacks providing a “promote to production” path for all the tested and ap-
proved changes.
• SAP Transport Management System (STMS) is used to move the change requests
(transports) from the development environment to the quality, training, and produc-
tion environments in an ABAP stack.
• SAP Change Management Service (CMS) of the NWDI is used to move Java object
changes in the Java stack.
• NetWeaver Developer Studio is the Java application development platform used in the
Java stack environments.
• The NWDI Design Time Repository (DTR) serves as a central repository for all
source files.
• The NWDI Component Build Service (CBS) serves as a central build environment for
Java applications.
• SAP NetWeaver Portal and Development Infrastructure usage types are good ex-
amples of a Java stack environment.
• SAP ERP (ECC) and SAP BW are good examples of an ABAP stack environment.
