Transport and Change Management 

Any changes that you make to programs and system configurations are recorded by the SAP system in the Change and Transport System (CTS). Within an SAP system, the Transport Organizer manages your changes in requests, which are then transported through the system landscape and into the production system by the Transport Management System (TMS).

Any changes to Repository objects that you manage in the CTS apply in all clients. However, you can also make client-specific developments and transport them into the relevant clients only.
