The change analysis function provides an overview of the changes that have been applied to the managed systems. It also displays the number of changes per system, change category, and day. You can access it from the Root Cause Analysis work center. 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 and automatically takes you to the change reporting data viewer for the details and history of a changed item.

Integration

Change analysis is part of end-to-end analysis within root cause analysis. Change analysis is based on the data of the configuration and change database (CCDB) within SAP Solution Manager. Any change figures are stored in SAP NetWeaver BW, and the configuration data itself is stored in the configuration stores of the CCDB. The configuration stores are part of the CCDB and contain all configuration details. Change analysis uses change reporting data viewer to display detailed configuration data.

Prerequisites

You have the required authorizations for the Root Cause Analysis work center.

For more information on prerequisites and change analysis system architecture, see the E2E Change Analysis User Guide on SAP Service Marketplace at   http://service.sap.com/diagnostics   Tools in End-to-End Root Cause Analysis  .

Features

  • Overview of changes, displayed by systems and their product instances.

  • Summary that shows which product instance had the most changes and which had the most recent changes.

    The table view displays the number of changes per configuration store and date. Clicking on a cell that is highlighted in green starts the change reporting for the configuration store and date.

    The default time frame is This week. You can change the time frame by choosing one of the entries in the Timeframe field or by specifying any time frame using the option Custom selection. Based on the selected time frame, the data is read from SAP NetWeaver BW.

  • History of changes made over the past 2 years that displays the number of changes per quarter (current quarter and the 8 previous quarters).

    The Last Change Date table helps you identify the product instance and change group with the most recent reported change.

  • Changes by product instance

    For each product instance, a change summary and details are displayed. Details for product instances comprise, for example, views for parameters, security, transport requests, SAP Notes, and miscellaneous details. These criteria are different for each product instance. From the detail data, you can continue to perform a more detailed analysis. For example, you can drill down into the details on changed parameters for a product instance.

    For example, to display a list of parameters that were changed on a certain day, select the Parameter view and click a cell that is highlighted in green and contains the number of changes. The system displays the parameter details in a new window. If the change was recorded in a transport request, you can find the details in the managed system.

  • Display of host data

    For the selected systems, data of all hosts is displayed on the Hosts tab page in case the host was affected by a change. You can display the details of a change by clicking on a cell with a green background.

Note Note

Collection of the change data starts with the date when the configuration stores are filled for the first time. Only changes of a product instance configuration made after this date can be displayed in the change analysis. Thus it is not possible to report any changes that were made before the change analysis function was set up. Therefore, the history of changes that were made during the past two years can also only display changes after the change analysis function was set up.

The configuration stores are shown in change reporting. The change analysis can only report changes if there were any.

End of the note.

Activities

  1. To start a change analysis, choose End-to-End Analysis on the Root Cause Analysis work center.

  2. In the Detailed Selection list, select one or more systems for which you want to conduct the analysis.

  3. In the header area of the Detailed Selection list, choose Change Analysis. You can decide whether you want to display the analysis in a new window or on the same screen.

  4. The system automatically creates an Overview tab page and an additional tab page for each product instance of the selected systems and the host. The tab descriptions contain the system ID and the product instance.

  5. Choose the Overview tab page or one of the tab pages for the product instances. Cells with a green background color contain links to detailed data. You can go there by choosing the link.
