SAP S/4HANA Error 4708: Remote Source Adapter Failure
Description
Error 4708, ERR_DPSERVER_ADAPTER_FAILURE, indicates a problem connecting to or communicating with a remote data source via its configured adapter. This typically occurs when SAP S/4HANA attempts to access external data, but the underlying data provisioning mechanism encounters an issue.
Error Message
ERR_DPSERVER_ADAPTER_FAILURE: Adapter failure occurred on remote source
Known Causes
4 known causesNetwork Connectivity Issues
The S/4HANA system or the Data Provisioning Agent cannot establish a stable network connection to the remote source due to outages or intermittent drops.
Incorrect Remote Source Configuration
Connection parameters, such as host, port, credentials, or other adapter-specific settings for the remote source, are misconfigured or outdated.
Remote System Unavailability
The target remote data source system is offline, unreachable, or experiencing issues that prevent the adapter from establishing a successful connection.
Firewall or Security Block
A firewall, proxy, or security group is blocking the necessary ports or IP addresses required for S/4HANA or the Data Provisioning Agent to connect.
Solutions
4 solutions available1. Verify Remote Source Connection Parameters easy
Ensure all connection details for the remote source are correctly configured and accessible.
1
Navigate to the SAP S/4HANA transaction for managing Virtual Data Model (VDM) or Data Federation. This is typically done through SAP Fiori apps like 'Manage Virtual Data Sources' or by accessing transaction `SPRO` -> SAP Reference IMG -> SAP NetWeaver -> Application Server -> ABAP Web Services -> Configuration -> Manage Service Definitions (though the specific path might vary slightly based on S/4HANA version and customizations).
2
Locate the specific remote source configuration that is failing.
3
Review and re-enter all connection parameters, including:
4
Hostname or IP address of the remote system.
5
Port number.
6
Database type (e.g., HANA, Oracle, SQL Server).
7
Database name or service name.
8
Authentication details (username, password, or other credentials). Ensure these are current and have the necessary permissions on the remote source.
9
Save the changes and attempt to re-establish the connection or trigger the operation that caused the error.
2. Check Network Connectivity and Firewall Rules medium
Verify that the S/4HANA system can reach the remote source over the network and that no firewalls are blocking communication.
1
From the SAP S/4HANA application server, attempt to ping the remote source hostname or IP address.
ping <remote_source_hostname_or_ip>2
If ping fails, investigate network routing and ensure that the S/4HANA server can resolve the hostname of the remote source.
nslookup <remote_source_hostname_or_ip>3
Verify that the relevant network ports required by the remote data source adapter are open on any firewalls between the S/4HANA application server and the remote source. Common ports include 3xx15 for HANA, 1521 for Oracle, 1433 for SQL Server, etc.
4
If using SAP HANA Database as the remote source, ensure that the `nameserver` port (default 3xx15) and the SQL port (default 3xx13) are accessible.
5
If you suspect firewall issues, coordinate with your network administrators to temporarily open the necessary ports for testing or permanently configure them.
3. Review SAP Gateway Service and RFC Destinations medium
Ensure that the SAP Gateway services required for remote communication are active and properly configured, especially if the remote source relies on RFC.
1
In SAP S/4HANA, navigate to transaction `SMGW` (Gateway Monitor).
2
Check the status of registered programs and connections. Look for any errors or unexpected disconnections related to the remote source.
3
Verify that the necessary SAP Gateway services are running. You can check this in transaction `SM21` (System Log) and `SM51` (SAP Servers) for any gateway-related errors.
4
If the remote source uses RFC, navigate to transaction `SM59` (RFC Destinations).
5
Locate the RFC destination configured for the remote source and perform a connection test.
6
Examine the error messages from the RFC connection test. If the test fails, review the destination's configuration, including program ID, gateway host, and gateway service.
7
Ensure that the `sapgw<nn>` service is running on the gateway host where the RFC destination is configured, where `<nn>` is the system number.
4. Analyze SAP HANA Database Traces and Logs advanced
Investigate SAP HANA database traces and logs on both the S/4HANA and remote source systems for detailed error information.
1
On the SAP S/4HANA system, check the system log for any relevant error messages related to the remote source adapter. Use transaction `SM21`.
2
If the remote source is a SAP HANA database, access the HANA database traces. This can be done via SAP HANA Studio, SAP HANA Cockpit, or by accessing the HANA trace files directly on the server.
3
Look for traces related to `indexserver`, `nameserver`, or specific adapter processes that might be failing. Search for keywords like 'adapter failure', 'remote source error', or specific error codes from the `ERR_DPSERVER_ADAPTER_FAILURE` message.
4
If the remote source is a non-HANA database, check its native logging and trace mechanisms for errors that occur during the connection attempt or data retrieval from the S/4HANA system.
5
Correlate timestamps from S/4HANA logs with HANA or remote database logs to pinpoint the exact moment and context of the failure.
6
If specific error messages or stack traces are found, search SAP Notes and SAP Community for known issues and solutions related to those details.
