SAP Transport Management

Landscape

What is a Transport Request? Transport Requests (TRs)  are also known as Change Requests. It is a kind of 'Container / Collection' of changes that are made in the development system . It also records the information regarding the type of change, purpose of transport, request category and the target system.

Create a Change Request Change Request can be created in two ways: Automatic – Whenever creating or modifying an object, or when performing customizing settings, system itself displays the 'Dialog box' for creating a change request or mention name of an already created request, if available. Manually – Create the change request from the Transport Organizer, and then enter required attributes and insert objects.
