In SAP R/3, a change request represents a list containing objects to be transported to the production environment. The change request as such contains the purpose of the change, the change type, the request
category and the target system. Change requests are commonly referred to as transports in SAP terminology. One important thing to note is that a change request may consist of more than one change tasks.

At the time of creation of a change request, SAP R/3 assigns a change request number to the transport request. In case user is using the Workbenck Organizer in SAP, the target system and the type of request
are assigned automatically to the change request. There are two types of change request categories in SAP Workbench organizer. The "SYST" category contains ABAP development object and general customizing. The "CUST" category contains objects relevant to client specific cutomizing.

Lastly, when changes have been made, and the change tasks have been released, the change request can be released. Transportable change requests are released to the treansport system. The transport system
exports the objects and keeps a log of all transports. To display change requests, user can choose the following menu or simply go to transaction SE09.
