You work through the steps below using the TREX admin tool (standalone).
Configuration of the RFC connection with the TREX admin tool (standalone) is only available as of SAP Basis Component SAP_BASIS 6.20 SP58, 6.40 SP16, and 7.0 SP6. If you are using TREX with an SAP system based on an earlier support package, you have to configure the RFC connection manually as described in the SAP NetWeaver 04 Installation Guide for Search and Classification (TREX) 6.1. You can find this guide on the SAP Service Marketplace at service.sap.com/instguides .
