R3trans is called with the following command:
fork()
spawn()
CreateProcess()
The global parameter file determines which R3transis used for each SAP System. If parameter r3transpath is incorrectly specified, no exports or imports can be performed. The implemented default value r3transpath = R3trans or for Windows r3transpath = R3trans.exe is adequate.
The complete path must be specified for IBM IBM i. It is a symbolic link pointing to the program R3transdb4 in the SAP kernel library, for example, R346COPT, which must be installed locally. The value must be /usr/sap/$(SYSTEM)/SYS/exe/run/R3trans.
