When we tried to connect SAP R/3 System (Ver. 4.7) from xMII server, we were getting the error “Fatal Error: JCOProxy error: User not authorized. Session terminated”. The error continued to happen despite entering the correct user name and Password. The user ID, which was used to connect, was having the profiles “sap_all” and “sap_new”.
Screenshot of the Error.
The SAP backend system (SAP R/3 4.7) is a Web Application Server (WAS) of version 6.20, and it converts the password into UPPERCASE. Therefore all passwords in lowercase were failing in RFC, which got resolved by changing the Password to UPPERCASE.
The issue was resolved by entering the password to UPPERCASE.
