  • What is the cause and solution for SAP error message ESH_ADM_MSG191 - Destination NO TREX is only allowed for Enterprise Search ?

    The SAP error message ESH_ADM_MSG191 with the description "Destination NO TREX is only allowed for Enterprise Search" typically occurs in the context of SAP Enterprise Search when there is an issue with the configuration of the TREX (Text Retrieval and Extraction) system. This error indicates that the system is trying to use a destination that is not properly configured for TREX.

    Cause:

    1. Incorrect Destination Configuration: The destination "NO TREX" is meant to indicate that there is no TREX system available. This can happen if the system is incorrectly configured to use this destination when it should be pointing to a valid TREX instance.
    2. Missing TREX Instance: If the TREX instance is not installed or not running, the system will not be able to connect to it.
    3. Enterprise Search Configuration: The configuration for Enterprise Search may not be set up correctly, leading to the system trying to access a non-existent TREX instance.

    Solution:

    1. Check TREX Configuration:

      • Go to the SAP system and check the configuration of the TREX system. Ensure that the TREX instance is installed and running.
      • Use transaction code TREXADMIN to access the TREX administration tool and verify the status of the TREX instance.
    2. Adjust Destination Settings:

      • If you are using the "NO TREX" destination, ensure that it is appropriate for your use case. If you need to connect to a TREX instance, update the destination settings to point to the correct TREX instance.
      • You can check and modify the destination settings in transaction SM59 (RFC Destinations).
    3. Enterprise Search Configuration:

      • Review the configuration settings for Enterprise Search in transaction ESH_COCKPIT. Ensure that the settings are correctly pointing to the TREX instance.
      • If you are not using Enterprise Search, ensure that the configuration does not mistakenly reference it.
    4. Restart Services:

      • If changes are made to the TREX configuration or the destination settings, consider restarting the TREX services to ensure that the changes take effect.
    5. Consult Documentation:

      • Refer to the official SAP documentation for Enterprise Search and TREX for detailed configuration steps and troubleshooting tips.
