Connections Between Several Domains


Transports can be performed between different domains using "external systems".

External systems are like virtual systems. This means that they are accessed via a communications system. However, a separate transport directory is defined additionally for this type of system. This directory can either reside on a disk partition that can be accessed by an R/3 System in the other domain, or it is on an exchangeable data medium.


To perform transports between two transport domains, proceed as follows:

  1. In each transport domain, define an R/3 System that really exists in the other transport domain as an External System.
  2. As the communications system, choose an R/3 System that can access the intermediate directory or the drive of the exchangeable data medium.
  3. Define the platform-specific path to it as the transport directory of the respective external system.
  4. You can now route transports to the external system. All necessary files are stored in the external transport directory.

    Using the queue display of the external system, you can check which transport requests have already been created there.

  5. To transfer them to the other domain, you must adjust the import queue in the relevant target system (see the section Special Features when Using Several Transport Directories) once the transport data has been made accessible.
  6. If you have chosen a target system in the source domain that does not exist in the target domain, it is still possible to transfer the transport requests.

To do this, define another external system in the target domain with the name of the original target system. From the queue display of this system, you can route the transport requests to the R/3 System you have chosen.
