SAP S/4HANA Error 1030: Communication Send Failure
Description
This error indicates a general failure during an attempt to send data or a communication request from SAP S/4HANA. It typically occurs when the system tries to transmit information to an external system, another SAP module, or a network service, but the send operation does not complete successfully.
Error Message
ERR_COM_SEND
Known Causes
4 known causesNetwork Connectivity Problems
The SAP S/4HANA system or the target recipient system may have unstable or no network connection, preventing data transmission.
Misconfigured Communication Settings
Communication channels, RFC destinations, or integration settings within SAP S/4HANA might be incorrectly configured, leading to send failures.
External System Unavailability
The external system or service that SAP S/4HANA is attempting to send data to is offline, overloaded, or not responding.
Firewall or Security Blocks
Firewalls, security policies, or proxy settings on either end may be blocking the outgoing communication from SAP S/4HANA.
Solutions
4 solutions available1. Verify Network Connectivity and Firewall Rules easy
Ensures basic network communication is established between S/4HANA and the target system.
1
From the S/4HANA application server, attempt to ping the target system's hostname or IP address.
ping <target_hostname_or_ip>2
If ping is successful, check for open ports on the target system that S/4HANA needs to communicate with. Consult your interface documentation for required ports.
telnet <target_hostname_or_ip> <port_number>3
Review firewall rules on both the S/4HANA application server side and the target system side to ensure the necessary ports are allowed for inbound and outbound traffic.
N/A (Requires network administrator intervention)4
If using SAProuter, verify its configuration and that it's running correctly, allowing traffic to the target system.
N/A (Requires SAProuter administration)2. Check SAP Gateway Configuration and Status medium
Ensures the SAP Gateway, responsible for inter-process communication, is running and properly configured.
1
Access transaction SMGW on your S/4HANA system.
N/A2
Verify that the Gateway is running. You should see a green status indicator. If not, attempt to start it.
N/A3
Go to 'Goto' -> 'Expert Functions' -> 'TCP/IP Connections'. Check if the RFC destination pointing to the target system is correctly configured and active.
N/A4
In SMGW, go to 'Goto' -> 'Logged On Clients'. Ensure the client or system trying to send the communication is listed and active.
N/A5
Check the Gateway log files for any errors. These are typically located in the work directory of the application server.
N/A (Requires OS access to application server)3. Validate RFC Destination and Target System Service medium
Confirms that the Remote Function Call (RFC) destination within S/4HANA is correctly set up and the service on the target system is listening.
1
Access transaction SM59 on your S/4HANA system.
N/A2
Locate the RFC destination that is failing. It will likely be of type 'T' (TCP/IP) or 'G' (ABAP Connections).
N/A3
Execute a 'Connection Test' and 'Unicode Test' from SM59 for the problematic RFC destination. Address any reported errors.
N/A4
Verify the 'Program ID' if it's an 'ABAP Connections' type. Ensure it matches the registered program on the target system.
N/A5
On the target system, ensure the service or application that should receive the RFC call is running and listening on the expected port and interface.
N/A (Requires target system administration)4. Analyze System Logs for Deeper Insights advanced
Provides a comprehensive approach by examining various system logs for specific error messages and context.
1
Access transaction SM21 (System Log) on your S/4HANA system. Filter by the time the error occurred and look for entries related to communication failures or the specific error code 1030.
N/A2
Check the Gateway logs (SMGW -> Goto -> Trace File -> Display). Look for detailed error messages that might indicate network issues, timeouts, or incorrect configurations.
N/A3
Examine the application server's work process trace files (SM50 -> Trace -> Display). These can sometimes provide more granular details about the communication attempt and failure.
N/A4
If the communication involves an external system (e.g., web service), check the logs of that external system for corresponding error messages. This is crucial for identifying if the issue originates from S/4HANA or the target.
N/A (Requires target system log analysis)5
Review the ST05 (SQL Trace) or ST12 (Single Transaction Trace) if the communication involves database operations that might be failing due to underlying data issues or resource constraints.
