Change Diagnostics capabilities within SAP Solution Manager comprise the following applications; End-to-End Change Analysis, Change Reporting, Configuration Validation and the Configuration and Change Database as central configuration item repositories.
Change Diagnostics Capabilities are available after a SAP Solution Manager Managed System Configuration has been performed for a managed system. It detects and records common technical changes in a managed system. A change tracking is performed independent of a change management process (such as one introduced by Change Request Management or Quality Gate Management). It is one of the core functionalities of SAP Solution Manager.
Changes are tracked and stored using the Configuration and Change Database (CCDB). The CCDB saves the configuration data of managed systems in configuration repositories and allows tracing changes. The configuration data is collected daily by the extractor framework, and uploaded from the managed systems to CCDB.
