SAP S/4HANA Error 5443: Failed to Open Third-Party Stream
Description
This error indicates a problem when SAP S/4HANA attempts to process data using a third-party filter, specifically when trying to open a data stream from a memory buffer. It often occurs during operations involving external document processing, data import, or integration with external content management systems.
Error Message
ERR_TEXT_FCA_OPEN_STREAM_FROM_MEM_BUFFER
Known Causes
4 known causesCorrupted or Incompatible Third-Party Filter
The external filter library responsible for processing the data stream might be damaged, outdated, or incompatible with the current SAP S/4HANA version. ⚠
Insufficient System Resources
The system may lack sufficient memory or other resources required to create and manage the memory buffer for the third-party filter stream. 💻
Incorrect Integration Configuration
Parameters or settings for integrating with the third-party application or content repository are misconfigured, preventing proper stream handling. ⚙
Corrupted or Invalid Data Stream
The data being processed by the third-party filter might be corrupted or in an unexpected format, causing the filter to fail when attempting to open the stream. ⚠
Solutions
3 solutions available1. Restart SAP Application Server Instance easy
A simple restart can resolve transient memory issues affecting stream handling.
1
Log in to the SAP S/4HANA server where the application instance is running.
2
Open the SAP Management Console (SAP MMC) or use the command-line tools to stop the relevant application server instance.
stopsap <SID>3
Wait for the instance to completely shut down.
4
Start the SAP application server instance again.
startsap <SID>5
Verify that the error 5443 no longer occurs during normal operations.
2. Review and Adjust SAP Work Process Configuration medium
Incorrectly configured work processes might lead to memory allocation issues for stream operations.
1
Access transaction RZ10 in your SAP S/4HANA system.
2
Select the profile of the instance experiencing the error.
3
Choose 'Display' to view the current profile parameters.
4
Pay close attention to parameters related to memory management and work processes, such as:
ztta/roll_area
ztta/roll_extend
EM/MAX_SIZE
HEAP/MAX_SIZE5
Consider increasing these values incrementally if they appear to be too restrictive, especially if the system is under heavy load or processing large datasets. Consult SAP Notes for recommended values based on your system's sizing and workload.
6
Save the changes and activate the profile.
7
Restart the SAP application server instance for the changes to take effect.
3. Investigate Third-Party Component Integration Issues advanced
The error indicates a problem with a third-party stream, suggesting an issue with the external component or its integration.
1
Identify the specific third-party component or service that is being accessed when error 5443 occurs. This might require analyzing ST22 dumps or SM21 logs for more context.
2
Check the logs of the third-party component for any errors or warnings that coincide with the SAP S/4HANA error.
3
Verify the network connectivity and firewall rules between the SAP S/4HANA server and the third-party system. Ensure that the necessary ports are open and that there are no network interruptions.
4
Confirm that the third-party component is running and functioning correctly. Try to access its services directly from a client or another system to rule out issues with the component itself.
5
Review the configuration of the integration point between SAP S/4HANA and the third-party component. This might involve checking RFC destinations, web service configurations, or other integration interfaces.
6
If the issue persists, contact the vendor of the third-party component for support, providing them with the SAP S/4HANA error details and any relevant logs.
