SAP S/4HANA Error 1031: Communication Receive Failure
Description
This error indicates that the SAP S/4HANA system encountered a problem while attempting to receive data or a response from another component or external system. It typically occurs during data exchange, integration processes, or when calling remote services, preventing successful completion of the operation.
Error Message
ERR_COM_RECEIVE
Known Causes
4 known causesNetwork Connection Failure
The SAP S/4HANA system could not establish or maintain a stable network connection with the required communication partner or service.
Remote System Unresponsive
The external system or service that SAP S/4HANA was trying to communicate with was offline, overloaded, or not responding.
Misconfigured Communication
The communication settings, such as RFC destinations, service endpoints, or proxy settings, are incorrectly configured in SAP S/4HANA.
Firewall/Security Block
A firewall, proxy, or other security measure is preventing the incoming data or response from reaching the SAP S/4HANA system.
Solutions
4 solutions available1. Network Connectivity and Firewall Check medium
Ensures basic network communication between S/4HANA components and external systems.
1
Identify the source and destination systems involved in the communication that is failing. This could be the S/4HANA application server, the database server, or an external system connecting to S/4HANA.
2
On the source system (e.g., S/4HANA application server), verify that the destination system is reachable using `ping` or `telnet` to the relevant port.
ping <destination_ip_or_hostname>
telnet <destination_ip_or_hostname> <port>3
On the destination system (if applicable), perform similar connectivity checks back to the source system.
ping <source_ip_or_hostname>
telnet <source_ip_or_hostname> <port>4
Consult with network administrators to ensure that no firewalls (network firewalls, OS-level firewalls like `iptables` or Windows Firewall) are blocking the communication ports between the source and destination systems. Verify that the necessary ports are open and configured correctly.
5
If using SAProuter, ensure it is running and correctly configured to allow traffic between the relevant systems and ports.
2. SAP Gateway (ICM) Service Restart easy
Resets the Internet Communication Manager (ICM) which handles HTTP/HTTPS and other network protocols for S/4HANA.
1
Log in to the S/4HANA application server as a user with administrative privileges (e.g., DDIC or a user in the SAP_ALL profile).
2
Access transaction `SMICM` (Internet Communication Manager).
3
Navigate to 'Administration' -> 'Global' -> 'Restart'. Confirm the restart when prompted.
4
Alternatively, use the `icmon` command-line tool on the application server to restart the ICM. This is often preferred for scripting or remote administration.
cd /usr/sap/<SIDs>/<Instance>/work
./icmon -p -f <InstanceNumber>
./icmon -t5
Monitor the ICM status in `SMICM` after the restart to ensure it comes back online successfully.
3. Database Connection and Resource Check medium
Verifies the stability and availability of the underlying SAP HANA database connection.
1
Log in to the SAP HANA database as a user with administrative privileges (e.g., SYSTEM user).
2
Check the status of the SAP HANA database services. Ensure all critical services are running.
SELECT * FROM SYS.SERVICES;3
Review the SAP HANA alert files for any critical errors or warnings related to network, memory, or disk I/O that might be impacting communication.
4
Verify that the database listener is running and accessible from the application server. For SAP HANA, this typically involves checking the `nameserver` and `indexserver` processes.
5
Check for any long-running queries or transactions that might be consuming excessive database resources and potentially causing timeouts or connection issues.
SELECT * FROM SYS.PROCEDURES WHERE HOST = '<hostname>' AND PORT = <port>;
SELECT * FROM SYS.ACTIVE_STATEMENTS;6
Ensure there are sufficient resources (CPU, memory, disk space) on the database server.
4. SAP Notes and Patch Level Verification advanced
Addresses potential bugs in SAP software that are known to cause communication failures.
1
Identify the specific SAP S/4HANA component or module involved in the failing communication. This might be determined from the transaction code, error message context, or system logs.
2
Access the SAP Support Portal (launchpad.support.sap.com) and search for SAP Notes related to 'ERR_COM_RECEIVE', 'Communication Receive Failure', or specific error codes within the context of your S/4HANA version and the affected component.
3
Pay close attention to SAP Notes that mention compatibility issues, network configuration, or specific bug fixes for the ICM, Gateway, or database connectivity.
4
Check the current patch levels of your SAP S/4HANA system, including the kernel, SAP_BASIS component, and any relevant application components. Compare these to the recommendations in the identified SAP Notes.
5
If a relevant SAP Note is found and a patch level is out of date, plan and execute the necessary support package updates or individual corrections according to SAP's recommended procedures. This may involve using transaction `SPAM`/`SAINT` or other relevant tools.
