Implementing and Upgrading SAP Solutions 
This component performs the following functions on business processes and scenarios in a project:
describe and document
configure
The SAP Solution Manager provides central access to all tools, methods, documents and other data required in the implementation environment. You can use implementation contents, delivered with the SAP Solution Manager and regularly updated, and adjust it to your requirements.
The Implementation contents comprise predefined scenario, process and configuration structures for SAP solutions and applications, with implementation-relevant instances of general documentation, preconfiguration, BC Sets and test cases. At the end of the implementation project, the implemented business scenarios and processes and system information is put in a customer-specific repository (Solution Directory), where they are available for production processing.
For Upgrade Projects the SAP Solution Manager supports both:
restarting an upgrade project
perform an upgrade project based on an implementation project
The scope of support for these upgrade-relevant activities with the SAP Solution Manager is the same as for an implementation project, plus some upgrade-specific functions:
a comparison tool which identifies release-specific changes or deletions, if you used SAP reference contents
an upgrade report which gets the upgrade-relevant configuration settings which you must adjust in upgrade or delta customizing, automatically, based on a connection to the target release system
Upgrade-relevant contents are also delivered with the SAP Solution Manager, as an upgrade roadmap and upgrade-specific business scenario and process contents. At the end of the upgrade project, changed or inserted business scenarios and processes and system information are put in a customer-specific repository (Solution Directory), where they are available for production processing.
