User can apply a released change set, whereby the configuration data in the business objects in the change set is made live in the database. Applying the change set can result in the addition of business objects in the target system, if the business objects did not already exist on the target system or the modification of business objects in the target system if the business objects already existed. The change set can then be transported to another system once the applied changes are successfully tested on the target system. For example, a change set is transported from a development system to a test system. The change set is applied in the test system and the underlying configuration data changes are successfully made live. If the configuration data changes are successfully tested on the test system, the change set can be transported to a production system.
A change set can also be created and applied in the same system for the purpose of reverting to an earlier working configuration data if application issues are discovered. Refer to Reverting to a Defined Set of Configuration Data for more details.
