SAP S/4HANA Error 473: SQL Adapter Configuration Issue
Description
This error indicates a critical problem with the configuration of an SQL adapter within SAP S/4HANA. It typically occurs when the system attempts to establish a connection to an external database or data source using an adapter with incorrect or incomplete setup parameters, preventing successful data exchange or process execution.
Error Message
ERR_SQL_ADAPTER_CONFIGURATION
Known Causes
4 known causesIncorrect Connection Parameters
The adapter configuration contains inaccurate details such as database host, port, username, or password, preventing a successful connection.
Missing or Corrupted Driver
Essential database drivers or adapter libraries required for the connection are either missing from the system or have become corrupted.
Insufficient Database Permissions
The user account or service account configured for the SQL adapter lacks the necessary read/write permissions on the target database.
Network Connectivity Issues
Firewall restrictions, incorrect network routes, or other network problems prevent the SAP S/4HANA system from reaching the target database server.
Solutions
3 solutions available1. Verify SQL Adapter Connection Parameters in SAP S/4HANA easy
Ensures the SQL adapter uses correct connection details to the target database.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to transaction code `SM59` (RFC Destinations).
3
In the 'RFC Destinations' tree, locate the RFC destination used by the SQL adapter. This is often an `R` (TCP/IP) or `3` (ABAP System) type destination.
4
Select the RFC destination and click the 'Display' button.
5
Under the 'Technical Settings' tab, verify the 'Target Host' and 'System Number' (for TCP/IP destinations) or 'Program ID' (for registered servers).
6
Under the 'Logon & Security' tab, confirm the correct 'User' and 'Password' or 'Trust Relationship' settings for accessing the target database.
7
Click the 'Connection Test' button to validate the configuration.
8
If the connection test fails, correct the parameters and re-test. Pay close attention to network accessibility and firewall rules between the SAP application server and the database server.
2. Check SAP S/4HANA Gateway Service Registration medium
Confirms that the SQL adapter's communication channel is properly registered with the SAP Gateway.
1
Log in to your SAP S/4HANA system using SAP GUI.
2
Navigate to transaction code `SMGW` (Gateway Monitor).
3
From the `SMGW` menu, choose 'Goto' -> 'Logged on Clients'.
4
Look for an entry corresponding to the SQL adapter's 'Program ID' (if it's a registered server type RFC) or the RFC destination name. The status should be 'Active'.
5
If the SQL adapter is not listed or is inactive, it indicates a registration issue. Ensure the external SQL adapter service is running and attempting to register with the SAP Gateway.
6
Check the SAP Gateway trace files (`dev_rd` in the work directory of the gateway process) for any errors related to registration.
7
If the SQL adapter is configured as a started task (e.g., a daemon or service on the external machine), verify that this task is running and has the correct configuration to connect to the SAP Gateway using the specified Program ID.
3. Review and Update SQL Adapter Configuration Files medium
Ensures the external SQL adapter's own configuration files are correctly set up.
1
Identify the server where the SQL adapter software is installed and running.
2
Locate the configuration file(s) for the SQL adapter. The exact location and filename depend on the specific SQL adapter product being used (e.g., SAP Data Services, Informatica, custom adapters). Common locations might be within installation directories or in configuration directories.
3
Open the configuration file(s) in a text editor.
4
Verify the following parameters are correctly set:
5
- **SAP S/4HANA Hostname/IP Address:** The address of the SAP S/4HANA application server or message server.
6
- **SAP S/4HANA System Number:** The SAP system number.
7
- **SAP Gateway Service Name:** The name of the Gateway service used for communication (e.g., `sapgw<NN>`).
8
- **Program ID:** The unique identifier used for registered RFC server connections.
9
- **Database Connection Details:** Hostname, port, database name, username, and password for the target database.
10
- **Security Settings:** Any authentication or encryption parameters.
11
Save the changes to the configuration file(s).
12
Restart the SQL adapter service or process for the changes to take effect.
13
Check the SQL adapter's log files for any new errors after restarting.
