If you have configured multiple transport domains (see Transport Management System - Setting Up a System Landscape) and want to make transports between systems in different domains, you can use domain links to link the two domains.
There must be a permanent network connection between the systems in the two domains, similar to the connection between systems within the same domain.
Linking two domains with a domain link involves two steps:
Requesting a Link Between Two Domains.
To request a link between two transport domains, proceed as follows:
The dialog box Request for Linking 2 Domains appears.
Your SAP System performs the following actions automatically:
You can now see that you have requested the domain link to the other domain in the system overview.
You now need to confirm the link between the two domains in the controller of the other domain.
Confirming a Link Between Two Domains.
To confirm a link between two transport domains, proceed as follows:
The two domain controllers now exchange all necessary information about the systems in their domains. This information is distributed to all systems in the domain whose controller you are currently logged on to. A transport profile is generated, which contains all systems in both domains.
The information about the systems in the other domain is not automatically distributed to the systems in the domain where you requested the domain link. This means that you must distribute the new configuration to these systems.
The passwords of user TMSADM are not propagated to the affected TMS domains. Use Program TMS_UPDATE_PWD_OF_TMSADM for this.
To reject a link between two domains, go to the system overview of the domain controller and choose.
You have created a domain link between two transport domains. You can now see all systems in both domains in the system overview and the import overview. You can now make transports between systems in two different domains.
