CTS (Change and Transport System) :

The CTS is the central tool for managing changes to customizing and repository data that we make in the IMG or ABAP workbench.

As we have discussed earlier, a transport request cab be either customizing request or ABAP workbench request.

A customizing request can be created by the customizing tool IMG.

An ABAP workbench request can be created by ABAP workbench tool. Any changes or objects we develop through ABAP workbench are stored in Repository tables of SAP database.

As an ABAP developer you will be working with ABAP workbench and thus you create work bench requests.

A functional consultant works with configuration tool IMG (SAP Implementation Guide) T-code SPRO, thus creating customizing requests.

Transport organizer: Transport organizer is the tool provided by SAP which records and documents all changes to objects in the repository and customizing. The transaction code for transport organizer is SE10 or SE09.

Transport organizer is fully integrated with ABAP workbench and customizing tool IMG. That means you can navigate in both directions from transport organizer to ABAP workbench and reverse also.
