Like the Transport Management System, Transport Express has the concept of a Domain Controller.
The domain controller does not need to be configured in any special way, it is simply the SAP system that the Transport Express client software connects to, and is where Transport Express configuration and application data is stored.
The server software runs mostly within the Transport Express domain controller. When necessary, the domain controller connects to the other SAP systems to gather transport request information and to perform transports. These connections are made using SAP’s remote function call (RFC) protocol.
It is recommended that a Solution Manager system be selected as the Transport Express domain controller. Please note however that there is no requirement for the Transport Express domain controller and TMS domain controller to be the same SAP system. In fact, a single Transport Express domain controller can manage transports for multiple TMS domains.
Note: All Transport Express users will require a user account in the domain controller system with a valid email address in order to receive email notifications. Each user must also be assigned with role /BTI/TE:CTS_USER to allow access to the relevant TE functions.
