Change Management Service (CMS) is part of SAP NetWeaver Development Infrastructure (NWDI). It is used to configure development landscapes and transport software changes.
To aid the central management of software developments, CMS communicates with the components Design Time Repository (DTR) and Component Build Service (CBS). A connection to System Landscape Directory (SLD) ensures that data such as software component definitions is stored centrally.
You use the CMS to perform the following tasks:
Configuration of a development landscape
Configuration and administration of tracks for the development and distribution of software component versions in a development landscape.
Transport of software changes between systems of one track and between tracks.
