• Key Concepts: 
  External SAP System is a system that is not part of the SAP landscape, but is connected to it. It can be used to transfer data between different SAP systems, such as between a development system and a production system. The BC-CTS Change & Transport System (CTS) is the tool used to manage the transport of objects between different SAP systems. 
  
  How to use it: 
  The CTS can be used to move objects from one system to another. This includes programs, tables, and other objects. The CTS also allows for the transport of data between different systems, such as from a development system to a production system. The CTS also allows for the transport of changes made in one system to another. 
  
  Tips & Tricks: 
  When using the CTS, it is important to ensure that all objects are properly transported and that no errors occur during the transport process. It is also important to ensure that all changes made in one system are properly transported to the other system.
