SAP S/4HANA Error 5195: Language Model Access Failed
Description
This error indicates that the SAP S/4HANA system or a specific application could not locate or access one or more required language identification models. These models are essential for features that automatically detect the language of text input, often utilized in natural language processing (NLP) or text analysis functionalities. It typically occurs when such features are invoked but the underlying models are unavailable or misconfigured.
Error Message
ERR_TEXT_COMMON_LANGUAGE_IDENTIFICATION_MODEL_ACCESS_FAILED
Known Causes
3 known causesIncomplete Model Deployment
The language identification models were not fully or correctly deployed during system setup or a recent update, leading to missing files.
Incorrect Model Path Configuration
The system's configuration points to an incorrect directory or path where the language identification models should be located.
Insufficient File Permissions
The SAP S/4HANA system or relevant service user lacks the necessary read permissions to access the directories containing the language models.
Solutions
4 solutions available1. Verify and Activate Language Models in S/4HANA easy
Ensures that the necessary language models are correctly configured and active within the S/4HANA system.
1
Access the SAP Fiori Launchpad and navigate to the 'Language Settings' or 'Manage Language Models' app (depending on your S/4HANA version and installed apps).
2
Identify the language model relevant to the operation that is failing. This might be explicitly mentioned in the error context or can be inferred from the functionality being used.
3
Check the status of the identified language model. If it is inactive or shows any errors, attempt to activate it. This might involve a 'Activate' or 'Deploy' button within the app.
4
If activation fails, consult the application logs (e.g., using transaction ST22 for ABAP dumps or SM21 for system logs) for more detailed error messages related to the language model activation process.
5
If the model is corrupted or missing, you may need to re-deploy or re-install it. This typically requires SAP support or a system administrator with appropriate authorizations.
2. Check Underlying Database Configuration and Connectivity medium
Investigates potential issues with the HANA database itself, including its configuration and connectivity, which might affect language model access.
1
Log in to your SAP HANA database server using an appropriate administrative user (e.g., SYSTEM).
2
Open the SAP HANA Cockpit or HANA Studio and navigate to the system overview. Check the overall health and status of the HANA database.
3
Verify that the necessary HANA services related to text analysis or language processing are running. This might include services like 'textanalysisservice'.
SELECT service_name, state FROM SYS.SERVICES WHERE service_name LIKE '%text%';4
Check for any recent database parameter changes or updates that might have affected language model handling. Review the HANA trace files for related errors.
5
Ensure that the HANA system has sufficient resources (CPU, memory, disk space) available, as language model operations can be resource-intensive.
3. Review and Correct S/4HANA System Parameters medium
Examines and adjusts relevant S/4HANA system profile parameters that control language processing and model access.
1
Access transaction RZ10 in your S/4HANA system to manage instance profiles.
2
Select the relevant instance profile and choose 'Display' to view the current parameters.
3
Search for parameters related to language processing, text analysis, or model loading. Common parameters might include those starting with 'is_text' or related to specific text analysis engines. For example, check parameters that define the path to language model files or the configuration of text analysis services.
4
Ensure that these parameters are correctly set and point to valid locations or configurations. If you are unsure about specific parameters, consult SAP documentation for your S/4HANA version or contact SAP support.
5
If any parameters are modified, save the profile changes and restart the relevant application server instances for the changes to take effect. This is a critical step and requires careful planning to minimize downtime.
4. Consult SAP Notes and Support for Specific Scenarios advanced
Leverages SAP's knowledge base and support channels for known issues and specific solutions related to the error.
1
Go to the SAP Support Portal (SAP ONE Support Launchpad) and search for SAP Notes using keywords like 'S/4HANA', 'Error 5195', 'ERR_TEXT_COMMON_LANGUAGE_IDENTIFICATION_MODEL_ACCESS_FAILED', and the specific functionality that is triggering the error.
2
Analyze the search results for relevant SAP Notes. Pay close attention to notes that describe the exact error message, the affected S/4HANA versions, and the recommended solutions, which might include specific patches, configuration steps, or workarounds.
3
If no relevant SAP Notes are found, or if the provided solutions do not resolve the issue, consider opening a ticket with SAP Support. Provide detailed information about your S/4HANA version, the exact error message, the steps to reproduce the error, and any troubleshooting steps you have already taken.
4
When interacting with SAP Support, be prepared to provide system logs (ST22, SM21, HANA traces), system configuration details, and potentially allow remote access for SAP engineers to diagnose the problem.
