For several years now, SAP has been supporting the development of customer objects with its ABAP Development Workbench and NetWeaver Development Infrastructure (NWDI). Another professional tool, the SAP Implementation Guide (IMG), helps administrators configure their system (customizing) by allowing them to make all the necessary settings.
Every single change to the system is captured in transport requests. Companies can use the SAP Transport Management System (TMS) to forward these transport requests to the test and production systems – the introduction of the extended Change and Transport System (CTS+) has also made it possible to include non-ABAP SAP applications.
