Change analysis is based on the data of the configuration and change database (CCDB). Any change figures are stored in SAP NetWeaver BW, the configuration data itself is stored in the configuration stores of the CCDB.
The change analysis function provides an overview of the changes that have been applied to the managed systems and their product instances. You can access it from the Root Cause Analysis Group. It reports changes of configuration items of a system (for example, OS, DB, ABAP parameters, Java parameters, transport requests, and Support Packages) and serves as a central entry point for root cause analysis.
Change analysis helps you to keep track of the changes in your solution landscape. Your development system might behave differently than your production system. Or, J2EE instances of your productive system behave differently and you need to find out the reason. Therefore, regular snapshots of the configuration settings are taken and stored in the configuration and change database (CCDB) of SAP Solution Manager. With this information, the change analysis function enables you to identify the changes. The change analysis function provides the number of changes details and history of a changed item.
