Change and Transport System (CTS) is a tool that helps you to organize development projects in ABAP Workbench and in Customizing, and then transport the changes between the SAP systems in your system landscape. As well as ABAP objects, you can also transport Java objects (J2EE, JEE) and SAP-specific non-ABAP technologies (such as Web Dynpro Java or SAP NetWeaver Portal) in your landscape. For more information, see Transporting Non-ABAP Objects in Change and Transport System.
This documentation gives you an overview of how you can use CTS to organize your changes, as well as basic information on setting up your system and client landscape, and choosing a transport strategy. Read and follow this documentation when planning your development project.
