A system user (with the default name SAPJSF) handles communications between the user management engine (UME) and the user management of the SAP NetWeaver Application Server (AS) ABAP. You are not required to change the password of system users regularly. However, if you change the password of this user in transaction SU01, you must also change the password stored for this user in the AS Java database to match.
You must maintain the password of the system user for UME-ABAP communication, or the AS Java cannot start. If the AS Java cannot start, activate the emergency user and maintain the password of the system user in the RFC destination.
For more information, see Activating the Emergency User
For more information, see Maintaining RFC Destinations
If the test fails, go back and reenter the connection data and test the connection until you are successful.
The AS Java is now configured to support the new password of the system user for UME-ABAP communication.
