SAP Transport Management System in ABAP Systems
In this chapter we will study the theory and practice of SAP Transport Management in ABAP
systems. First, a number of concepts will be covered, followed by practical Transport Man-
agement setup, use, and troubleshooting techniques. This chapter will also cover best prac-
tices for setting up Transport Management in SAP systems.
Transport Management Concepts
Transport Management in SAP ABAP systems includes concepts such as the data movement
strategy between the three standard SAP System Landscapes (development, quality assur-
ance, and production); data packaging of ABAP source code changes and configuration
changes in the form of change requests or transport requests; exporting and importing the
transport requests using the SAP transport control program (tp); and coordinating database
updates and ABAP code generation by the tp program.
Data Movement Between SAP Systems
SAP development and configuration changes are done in the development system and then
are packaged for orderly movement to quality assurance and production systems after thor-
ough testing. During the installation of the SAP development system, a central transport dir-
ectory referred to as /usr/sap/trans is created. This directory is NFS-mounted (Network File
System mounted) to the quality assurance and production systems ( Figure 11-1 ) so that data
can be exported and imported using this as a central data area at the file system. The host,
which has the central transport directory, is usually referred to as a saptranshost. SAP trans-
port requests are exported out of the development system's database and are imported into the
quality assurance and production system's databases using a transport program utility called
tp.
