This example shows the configuration of a transport route from system TDV to system TQA. It is not important whether the route is a consolidation route or a delivery route. The system TDV is in the domain DOMAIN_A and accesses the transport directory trans_a; the system TQA is in the domain DOMAIN_B and accesses the transport directory trans_b.

This graphic is explained in the accompanying text

The system TQA is configured as an external system in the domain DOMAIN_A. The transport route is created between TDV and TQA in the domain DOMAIN_A. The transport directory trans_ext is assigned to the external system TQA. The system TDV is configured in the domain DOMAIN_B as an external system with the transport directory trans_ext. Transports between the two domains are made through the transport directory trans_ext, which can be accessed by both domains. This means that two adjustment steps are required for transports between TDV and TQA. The first step copies all transport files (data files, cofiles, and buffers) from requests flagged for import into TQA to the directory trans_ext. This adjustment step is performed in the domain DOMAIN_A. Transport requests for TQA can then be seen by systems in the domain DOMAIN_B as well. A second step copies the transport data for TQA from the directory trans_ext to the directory of the 'real' system TQA. This step is performed in DOMAIN_B.

Configuration of External Systems

External systems represent systems that are in a different domain. The TMS needs to specify how an external system accesses the transport directory.

This graphic is explained in the accompanying text

In this example, the system TDV serves the domain DOMAIN_A as a communication system for the external system TQA. This means that you must configure the SAP servers of the system TDV so that they can access the directory trans_ext. In the same way, the system TQA in the domain DOMAIN_B must be able to access the directory trans_ext.


Make sure that you set the access authorizations so that files created by the system TDV in the directory trans_ext can be viewed and changed by the system TQA.


  1. Specify which directory is to be configured as the exchange directory trans_ext between the domains. Create the subdirectories bin, buffer, cofiles, data, log, sapnames, and tmp in this directory.
  2. Configure the access to the transport directory trans_ext so that both systems TDV and TQA can view and change all subdirectories. User TQAADM in the system TQA must be able to read and overwrite files created by user TDVADM.
  3. Use the TMS to configure the external systems TDV and TQA in both domains, as described under Configuring External SAP Systems.
  4. Also configure the transport route from TDV to TQA in both domains.


You have used an external system to link two transport domains, and can now transport requests between systems in both domains.
