SAP Reference IMG
In the standard system, SAP delivers the SAP Reference IMG with each system. The SAP Reference IMG contains the full functionality of all possible Customizing settings across all countries and application components. It is structured hierarchically according to the application component hierarchy. All Customizing activities are assigned to one or more components. You choose the functions that you want to implement in your company from the application components. This results in individual Customizing projects for implementing the SAP system in your company.
