SAP S/4HANA Error 5544: Text Preprocessor Request Canceled
Description
Error 5544, 'ERR_TEXT_PREPROCESSOR_REQUEST_CANCELED', indicates that a request sent to the SAP S/4HANA text preprocessor service was unexpectedly canceled. This typically occurs during operations involving text analysis, indexing, or search functionality, suggesting an interruption before the processing could complete.
Error Message
ERR_TEXT_PREPROCESSOR_REQUEST_CANCELED
Known Causes
4 known causesSystem Resource Contention
The text preprocessor request was canceled due to high system load or insufficient resources on the SAP S/4HANA server.
Network Connectivity Issues
An unstable or interrupted network connection between the client, application server, and the text preprocessor service led to the request being terminated.
Preprocessor Service Instability
The underlying text preprocessor service itself might be experiencing an issue, is stopped, or is incorrectly configured, causing it to cancel incoming requests.
Application Timeout or Cancellation
The application initiating the text processing request timed out, or the operation was explicitly canceled by a user or another process.
Solutions
4 solutions available1. Restart Text Preprocessor Service easy
A simple restart of the Text Preprocessor service can resolve temporary glitches.
1
Access the SAP S/4HANA system's transaction codes.
2
Navigate to transaction SM51 (Servers).
3
Identify the server where the Text Preprocessor work process is running. Look for processes of type 'WP' with a description related to Text Preprocessor (e.g., 'Text Preprocessor' or similar).
4
Select the identified Text Preprocessor work process and choose 'Cancel' from the menu (or use the corresponding button). This will gracefully stop the process.
5
Wait a few moments for the process to terminate. Then, observe if a new Text Preprocessor work process automatically starts. If not, you might need to restart the SAP application server instance or specifically restart the Text Preprocessor service through system administration tools (e.g., SAP MMC on Windows or `sapcontrol` on Linux).
sapcontrol -nr <instance_number> -function StartService TextPreprocessor
# or
sapcontrol -nr <instance_number> -function Start6
Verify that the Text Preprocessor service is running and that the error no longer occurs.
2. Check System Resources and Load medium
Insufficient system resources or high system load can cause the Text Preprocessor to fail.
1
Access transaction SM50 (Work Process Overview) or SM66 (Global Work Process Overview) to monitor system load.
2
Look for any Text Preprocessor work processes that are consistently in a 'waiting' or 'heavy load' state.
3
Check overall system resource utilization, including CPU, memory, and disk I/O, using operating system tools (e.g., `top`, `htop` on Linux; Task Manager on Windows) or SAP's performance monitoring transactions (e.g., ST06, ST02).
4
If high resource utilization is observed, identify the processes or applications consuming the most resources. This might involve other SAP applications, background jobs, or system-level processes.
5
Consider optimizing or rescheduling resource-intensive background jobs or applications that are running concurrently with Text Preprocessor operations.
6
If the issue persists, it might be necessary to increase system resources (CPU, RAM) or tune system parameters related to work process management and memory allocation.
3. Investigate Text Preprocessor Configuration and Parameters advanced
Incorrect configuration of Text Preprocessor parameters can lead to this error.
1
Access transaction RZ10 (Profile Maintenance) to view and modify SAP system profile parameters.
2
Locate and review parameters related to the Text Preprocessor. Key parameters might include:
rdisp/txpre_max_wp (Maximum number of Text Preprocessor work processes)
rdisp/txpre_timeout (Timeout for Text Preprocessor requests)
profile parameter documentation in SAP Help Portal or SAP Notes.3
Ensure that `rdisp/txpre_max_wp` is set to an appropriate value based on your system's capacity and workload. A value too low can lead to queueing and timeouts, while a value too high can strain system resources.
4
Verify `rdisp/txpre_timeout`. If it's set too low, it might be canceling valid requests prematurely. Consider increasing it if your Text Preprocessor operations are known to be lengthy.
5
After making any parameter changes, save the profile and restart the SAP application server instance for the changes to take effect.
6
Consult SAP Notes for specific recommendations on Text Preprocessor parameter tuning for your S/4HANA version.
4. Analyze System Logs for Specific Errors medium
Detailed analysis of system logs can pinpoint the root cause of the Text Preprocessor cancellation.
1
Access transaction SM21 (System Log) to view the system log.
2
Filter the system log for entries related to 'Text Preprocessor', 'ERR_TEXT_PREPROCESSOR_REQUEST_CANCELED', or specific error messages that occurred around the time of the failure.
3
Examine the details of these log entries. They often contain more specific information about why the request was canceled, such as underlying database errors, memory dumps, or external service failures.
4
Access transaction ST22 (ABAP Runtime Errors) to check for any ABAP dumps that may have occurred concurrently with the Text Preprocessor error. Dumps can provide detailed stack traces and error information.
5
If the logs point to a specific database issue, investigate the database logs (e.g., SAP HANA trace files, alert logs) for corresponding errors.
6
Based on the log analysis, search the SAP Support Portal for relevant SAP Notes or known issues that match the error details. If no specific solution is found, consider opening a ticket with SAP Support, providing the detailed log information.
