Transport Layer
The transport layer defines the transport behavior of ABAP packages. Since packages are used as transport units, each individual package determines the transport behavior of all development objects contained therein – that is, whether and how a package and all its development objects are transported.
The assignment of a package to a transport layer ensures that all its development objects are connected to the Change and Transport System (CTS), thereby defining the integration and consolidation system for its development objects.
The transport layer defines:
- Whether the development objects of a package are assigned to a local (objects are kept only locally in a development system) or transportable change request
- The SAP system in which development objects are developed and changed
- Whether these objects are transported into a discrete system sequence or – through a well-defined path – into a consolidation system.
