Changes created in the development system must somehow be 
moved, then incorporated into the test system, then 
subsequently moved and incorporated into the production 
system. The SAP Correction and Transport System (CTS) 
serves this purpose and is the vehicle by which SAP moves 
objects such as programs, screens, configurations or 
security settings from one system to the next. 
Additionally, the CTS ensures consistency between systems 
by maintaining log entries for any attempted or completed 
activities. If used correctly, the CTS creates an effective 
and standardized procedure for managing and recording 
changes made to the system while providing an excellent 
mechanism for integrating either newly created objects or 
existing objects that have been altered to meet the 
customer?s needs



The CTS contains work bench organizer and transport 
system : 
               The workbench organizer is used to record 
and contol changes to the ABAP/4 development objects; 
               The transport system is used to move objects 
from an SAP dev.system to production system
