SAP S/4HANA Error 5187: Invalid Language Model Manager
Description
Error 5187, 'ERR_TEXT_COMMON_INVALID_LANGUAGE_MODEL_MANAGER', indicates that the system's language model management component is not correctly initialized or accessible. This typically occurs when SAP S/4HANA attempts to perform text-related operations, natural language processing, or utilize multi-language features, but encounters an issue with its underlying language model service or configuration.
Error Message
ERR_TEXT_COMMON_INVALID_LANGUAGE_MODEL_MANAGER
Known Causes
4 known causesIncorrect Configuration
The language model manager's settings within SAP S/4HANA or its integrated components are misconfigured, incomplete, or contain invalid parameters.
Missing or Corrupt Language Data
Essential language model files, dictionaries, or data sets required by the manager are either missing from the system or have become corrupted.
Service Unavailability
The external or internal service responsible for managing language models is down, unresponsive, or unreachable due to network issues or service failures.
Permission Restrictions
The SAP system or the executing user lacks the necessary read or execute permissions for the directories or files associated with the language model manager.
Solutions
4 solutions available1. Restart SAP System and Relevant Services easy
A simple restart can resolve temporary inconsistencies in the Language Model Manager.
1
Log in to your SAP S/4HANA system's operating system as a user with administrative privileges.
2
Execute the command to stop the SAP system. The exact command may vary based on your SAP installation and operating system, but typically it involves commands like `stopsap` or `sapcontrol -nr <instance_number> -function Stop`.
# Example for Linux/Unix
sapcontrol -nr <instance_number> -function Stop3
Wait for all SAP instances and processes to completely shut down. Monitor the process list to confirm.
4
Start the SAP system using the appropriate command, such as `startsap` or `sapcontrol -nr <instance_number> -function Start`.
# Example for Linux/Unix
sapcontrol -nr <instance_number> -function Start5
After the SAP system has fully started, log in to the SAP GUI and attempt the operation that previously triggered the error.
2. Verify and Re-register Language Models medium
This involves checking the status of language models and re-registering them if necessary.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to transaction code `SPRO`.
3
Follow the path: SAP Reference IMG -> SAP NetWeaver -> Application Server -> Basis Services -> Language -> Language Model Manager -> Define Language Model Manager.
4
In the 'Define Language Model Manager' screen, identify the entry that might be causing the issue. Look for any entries marked as 'inactive' or with error indicators.
5
If you suspect a specific language model manager is problematic, you can try to deactivate and then reactivate it. Select the problematic entry, click the 'Deactivate' button, and then the 'Activate' button. You might need administrator privileges for this.
6
If the issue persists or you're unsure which model is problematic, consider re-registering the language model. This might involve using a report like `RS_LANG_MODEL_REG` (consult SAP Notes for the exact report and parameters). Execute this report in transaction `SE38` or `SA38`.
# Example execution in SE38
Report: RS_LANG_MODEL_REG
Execute7
After re-registering, restart the SAP system (as per Solution 1) and test the functionality.
3. Check System Parameters and Profile Settings medium
Incorrect system parameters can lead to issues with language model management.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to transaction code `RZ10`.
3
Select the appropriate default profile for your instance and click 'Change'.
4
Review relevant profile parameters. While there isn't a single parameter directly named 'Language Model Manager', parameters related to application server behavior, memory management, or specific service configurations might be relevant. Common parameters to check include `rdisp/max_wprun_time`, `rdisp/wp_no_dia`, `abap/heap_area_dia`, and `abap/shm_attach_mode`.
5
Consult SAP Notes related to Error 5187 or general language model issues for specific parameter recommendations. If you find any suspicious or incorrect settings, adjust them cautiously.
6
Save the profile changes and restart the SAP system (as per Solution 1) for the new parameters to take effect.
4. Apply Relevant SAP Notes and Support Package Updates advanced
SAP frequently releases fixes and updates that address such errors.
1
Log in to the SAP Support Portal (launchpad.support.sap.com).
2
Search for SAP Notes related to 'SAP S/4HANA Error 5187' or 'ERR_TEXT_COMMON_INVALID_LANGUAGE_MODEL_MANAGER'. Use keywords like 'Language Model Manager', '5187', and your specific S/4HANA version.
3
Analyze the search results for relevant SAP Notes. Prioritize notes that are marked as 'Correction' or 'Information' and are applicable to your S/4HANA version and support package level.
4
If a relevant SAP Note is found, follow its instructions carefully. This might involve:
a. Manually implementing code corrections (if instructed and you have the expertise).
b. Downloading and applying a correction as a support package or a separate SAP Note.
a. Manually implementing code corrections (if instructed and you have the expertise).
b. Downloading and applying a correction as a support package or a separate SAP Note.
5
If the error is related to a broader issue, check for available Support Packages or Enhancement Packages for your SAP S/4HANA system. Applying these can resolve a multitude of underlying problems.
6
After applying any SAP Notes or support packages, perform a full SAP system restart (as per Solution 1) and thoroughly test the functionality that was failing.
