SAP TMS (Transport Management System) Tutorial
- Details
What is TMS?
TMS is used to move, manage, control, copy development objects and customizing settings in an orderly fashion across SAP systems in a landscape through pre-defined transport routes (RFC Connections). The transport process basically consists of exporting of objects out of the source SAP system and importing them into the target SAP system/s. TMS Stands for Transport Management System
Why do we need a Transport System?
The CTS components play an important role in the overall development and customization environment. CTS stand for Change and Transport System
CTS is an instrument for:
- Administering & controlling new development requests.
- Managing transports
- Recording of where and by whom changes are made
- Configuring systems landscape
Overview of CTS Components
- CTO (Change and Transport Organizer) – It's the main tool for managing, browsing, and registering the changes done on the repository and customizing objects. It's the central point for organizing the development projects. SE01 is the transaction with the new extended view.
- Transport Tools – The actual transports happen in the back-end at the OS level using transport tools, which are part of SAP Kernel and includes the program R3trans and the transport control program tp.

SAP System-Landscape
The system landscape (also known as SAP System Group) is the arrangement of SAP servers. Ideally, in a SAP environment, a three-system landscape is recommended. It consists of the
- Development Server – DEV
- Quality Assurance Server - QAS
- Production Server - PRD.
Transport cycle in a very basic sense is the release of new Developments/ Customizing Changes from DEV which are imported in both Quality and Production systems. However, import in PRD can happen only once integration Testing and quality check have been performed in QAS (and marked as checked).
What is Customizing? How does TMS help in Customizing
- Customizing is a process to adapt the SAP system according to the customer's need. To perform the customizing, users and consultants take help of SAP Reference Implementation Guide (IMG), which is accessible through transaction SPRO.
- Customizing is ideally done in DEV. The Transport Organizer (SE01) is used in conjunction with IMG to record and transport customized changes further.
- ABAP Dictionary Objects: Tables, Domains, Data elements, etc.
- ABAP Programs, function modules, menus, screens
- Documents, Application defined transport-objects, etc.
Most of the Workbench changes (though, not all), are cross-client, i.e. changes will be reflected in all the system clients of the target system. Objects transported from the source system overwrite objects in the target system that has the same names.
Clients and the type of Data in SAP System
- Conceptually, client is a technical and organizational independent unit, that contains its own set of data (Master Data, Application/ Operational data, Customizing Data)
- Clients create separate environments for users from different user groups or with a different purpose, within same SAP system, without actually using the different database.
- From the Technical point of view, a client is specified using 3-digit numeric ID, which also acts as the value for the table field 'MANDT', in the case of client-specific jobs.
