You can configure more than one RFC connection between a TREX system and an SAP system.
More than one application in an SAP system should access the same TREX system. For organizational and performance reasons, each application should use a separate RFC connection. This means:
There is a separate RFC destination for each application in the SAP system.
There is a separate TREX RFC server for each application in the TREX system.
The graphic below depicts this constellation.
For more information, see Initially Configuring the RFC Connection.
Create an RFC destination in the SAP system. To do this, use the Create: RFC Destination (SM59) function on the RFC: Current tab page in the Landscape: Connectivity window.
Choose Connect to test the connection.
Choose Repair All to update the TREX configuration.
