SAP S/4HANA Error 5442: 3rd Party Filter Stream Creation Failure
Description
This error indicates a critical issue when SAP S/4HANA attempts to create a filter stream from a memory buffer using a third-party component. It typically occurs during data processing, report generation, or document handling where external filtering mechanisms are involved, preventing the successful processing of data.
Error Message
ERR_TEXT_FCA_CREATE_STREAM_FROM_MEM_BUFFER
Known Causes
4 known causesCorrupted Memory Buffer Data
The data within the memory buffer intended for the third-party filter is corrupted or malformed, making it impossible to create a valid stream.
Outdated or Incompatible 3rd Party Filter
The installed third-party filter component is not compatible with the current SAP S/4HANA version or is outdated, leading to stream creation failures.
Insufficient System Resources
The system lacks sufficient memory or processing power to handle the creation of the filter stream, especially with large data sets.
Incorrect 3rd Party Component Configuration
The third-party filter component or its integration with SAP S/4HANA is incorrectly configured, preventing proper stream initialization.
Solutions
4 solutions available1. Investigate System Memory and Resource Utilization medium
This error often indicates insufficient system memory or high resource contention impacting stream creation.
1
Monitor overall system memory usage on the S/4HANA application servers and the underlying database servers. Look for sustained high memory utilization.
2
Check the SAP transaction SM50 (Work Process Overview) and SM21 (System Log) for any memory-related alerts or excessively long-running processes that might be consuming significant memory.
3
Utilize operating system tools (e.g., `top`, `htop` on Linux; Task Manager on Windows) to identify processes consuming the most memory on both application and database servers.
top -o %MEM
# or
htop4
If memory pressure is high, consider temporarily restarting non-critical S/4HANA services or application servers during a maintenance window to free up memory. For a permanent solution, investigate memory leaks or optimize resource allocation.
2. Review Database Parameters for Memory and Buffers advanced
Incorrectly configured database memory parameters can lead to stream creation failures.
1
Access the SAP HANA Studio or SAP HANA Cockpit and navigate to the system overview. Locate and review the database parameters related to memory allocation and buffer sizes.
2
Specifically, examine parameters such as `global_allocation_limit`, `shared_memory`, `heap_limit`, and any parameters related to the stream processing or caching mechanisms. Consult SAP Notes and documentation for recommended values based on your S/4HANA version and system size.
SELECT * FROM M_CONFIGURATION_PARAMETERS WHERE KEY LIKE '%memory%' OR KEY LIKE '%buffer%';3
If parameter values are significantly deviating from recommended settings or appear too low for the workload, consider adjusting them. **Caution:** Modifying database parameters requires careful consideration and should be done during a planned maintenance window after thorough testing.
ALTER SYSTEM ALTER CONFIGURATION ('global.ini', 'SYSTEM') SET ('key_name') = 'new_value' WITH RECONFIGURE;
-- Example: ALTER SYSTEM ALTER CONFIGURATION ('global.ini', 'SYSTEM') SET ('global_allocation_limit') = '60' WITH RECONFIGURE;4
After parameter changes, restart the SAP HANA database for the new settings to take effect. Monitor system performance closely after the restart.
3. Analyze and Optimize Specific Data Streams or Queries medium
A problematic data stream or an inefficient query might be the root cause of the failure.
1
Identify the specific S/4HANA transaction, report, or background job that is triggering this error. This information is usually available in the application log or the system log (SM21).
2
If a specific query is identified, analyze its execution plan using SAP HANA Studio or `EXPLAIN PLAN` functionality to identify potential inefficiencies, such as full table scans or complex joins on large datasets.
EXPLAIN PLAN FOR <your_sql_query>;3
Consider optimizing the query by adding appropriate indexes, rewriting complex logic, or reducing the amount of data being processed. If the stream involves third-party integration, review the data being sent and received for any anomalies or excessive data volumes.
4
If the issue is related to a specific data stream from a third-party source, work with the vendor to understand how the data is being prepared and transmitted. Ensure the data format and volume are within acceptable limits for S/4HANA processing.
4. Apply Latest SAP HANA and S/4HANA Patches and Updates medium
This error might be a known issue resolved by a SAP patch or update.
1
Check for the latest available SAP Notes related to error code 5442 and the message 'ERR_TEXT_FCA_CREATE_STREAM_FROM_MEM_BUFFER'. SAP frequently releases corrections for such issues.
2
Review the SAP Support Portal for the latest SAP HANA database revisions and S/4HANA feature pack updates. Look for security patches and bug fixes that might address memory management or stream processing.
3
Plan and execute the application of relevant patches or updates during a scheduled maintenance window. Ensure you have proper backups and a rollback plan in place.
4
After applying patches, thoroughly test the functionality that was previously causing the error to confirm the resolution.
