Analysing Dependencies of Upgrades 
In a typical project or solution landscape, business processes run across multiple connected technical systems, on which different SAP applications (such as SAP ERP, SAP CRM, and SAP SCM) are used in combination. Before you start an upgrade, analyze the technical/functional dependencies between separately installed product instances. The aim of the analysis project is to show the effect of a target product version planned for the upgrade for individual product instances on the existing connections to other SAP product instances.
Technical dependencies within technical systems (for example, if a technical system is used by several product systems as a hub) can also be taken into consideration. Since this analysis is based exclusively on the defined product system data, we recommend that you use the Landscape Verification Tool to verify your product data. For more information, see Landscape Verification Tool.
Start the analysis project, based on the project or solution landscape that you are currently using to operate your business processes. Select product systems for which you are planning an upgrade, and define a target product version in each case. Starting from this, you receive dependency statements about the connected product instances and, if there are any, upgrade-related SAP Notes. A critical dependency exists if the upgrade of a product instance to the target product version means that existing functions between this product instance and another product instance are no longer executable after the upgrade. If necessary, check alternative upgrade options until there are no more critical dependencies. You can also determine the best order to perform dependent upgrades.
Recommendation
To obtain detailed information about the effects of an upgrade on your current business processes, use the scenario and component list on the SAP Service Marketplace when planning the upgrade. For more information, see http://service.sap.com/scl.
For more information about the process, see Analyzing Dependencies in Upgrade Planning.
Integration
This tool has been conceived as a planning tool for initial orientation. It integrates the function of the Upgrade Dependency Analyzer on the SAP Service Marketplace with the recorded system data in the SAP Solution Manager system, taken from the Solution Manager System Landscape and the Solution Directory. Select a project or solution landscape with the tool and Upgrade Dependency Analyzer uses this system data for the planned upgrade to calculate dependency statements, which can be transparently stored in SAP Solution Manager.
Prerequisites
The basis for upgrade planning is an existing, fully recorded project or solution landscape. For further information about processing the system landscape, see System Landscape Tab.
The relevant process interfaces are recorded in the Solution Directory. For more information, see Create Interfaces for Business Process Monitoring and Assign Interface to Processes.

CautionThe same conditions apply for this tool in relation to the determined dependency statements as for the Upgrade Dependency Analyzer on SAP Service Marketplace. For more information, see http://service.sap.com/uda.
End of the caution.
Features
Selecting a project or solution landscape and planning upgrade options for individual product systems
Displaying process interfaces recorded in the Solution Directory and manual creation of additional interfaces for planning purposes
Automatic calculation of dependency statements
To do this, you select product systems and select the connections between the product instances. These connections are recorded in the Solution Directory using interfaces between the associated logical components. The system checks the effect of the planned target product version on the connected product instances. The calculated depdency statements are based on combinations of product instances and versions that are supported by SAP.
User-specific evaluation of the meaning of dependency statements
Automatic calculation of technical dependencies for several product instances installed on one technical system
