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 RequestChange 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.
