SAP S/4HANA Error 471: Invalid Data Source
Description
This error, ERR_SQL_INV_DATA_SOURCE, indicates that the SAP S/4HANA system is unable to locate or connect to a specified database data source. It typically occurs when an application or report attempts to access external data using a name that is either incorrectly defined, non-existent, or inaccessible.
Error Message
ERR_SQL_INV_DATA_SOURCE
Known Causes
4 known causesIncorrect Data Source Name (DSN)
The data source name specified in the configuration, application, or SQL query is misspelled or does not match any defined data source.
Missing Database Driver/Client
The necessary database client software or ODBC/JDBC driver for the specified data source type is not installed or configured on the SAP S/4HANA application server.
Network Connectivity Issues
The SAP S/4HANA system cannot establish a network connection to the database server hosting the data source due to firewall rules, network outages, or incorrect hostnames.
Insufficient Database Permissions
The user account or system connecting to the data source lacks the required database permissions to access the specified database or schema.
Solutions
3 solutions available1. Verify Data Source Configuration in SAP S/4HANA medium
Ensures the logical data source is correctly defined and points to a valid physical source.
1
Access the SAP S/4HANA system via SAP GUI.
2
Navigate to transaction code `RSA1` (BW Modeling Workbench) or the relevant data modeling transaction for S/4HANA (e.g., CDS view definition tools).
3
Locate the data source that is causing the error. This might involve searching by name or by the technical object that utilizes it.
4
Inspect the configuration of the identified data source. Pay close attention to the connection details, the underlying table or view, and any filters or mappings defined.
5
If the data source is pointing to a virtual data source or a CDS view, verify that the underlying tables or views exist and are accessible.
6
For physical data sources, confirm that the specified database connection is active and valid within SAP S/4HANA.
7
If any inconsistencies are found, correct the configuration. This might involve selecting a different table, updating connection parameters, or reactivating related objects.
8
Save the changes and re-run the process that triggered the error.
2. Check Underlying Database Object Existence and Permissions medium
Confirms that the physical database objects referenced by the data source are present and accessible.
1
Identify the underlying database object (table, view, etc.) that the SAP S/4HANA data source is expected to access. This information can usually be found within the data source configuration in transaction `RSA1` or relevant S/4HANA modeling tools.
2
Connect to the SAP HANA database directly using a suitable client tool (e.g., SAP HANA Studio, DB Visualizer, or command-line tools like `hdbsql`).
3
Execute a query to check for the existence of the identified database object. Replace `YOUR_SCHEMA` and `YOUR_TABLE_OR_VIEW` with the actual schema and object name.
SELECT * FROM "YOUR_SCHEMA"."YOUR_TABLE_OR_VIEW" LIMIT 1;4
If the object does not exist, it indicates a problem with the database schema or the object creation process. Investigate why the object is missing.
5
If the object exists, verify that the SAP S/4HANA database user (typically the `<sid>adm` user or a dedicated application user) has the necessary privileges (e.g., `SELECT`) to access this object. You can check privileges using SQL commands.
SELECT * FROM PUBLIC.GRANTED_PRIVILEGES WHERE OBJECT_SCHEMA = 'YOUR_SCHEMA' AND OBJECT_NAME = 'YOUR_TABLE_OR_VIEW' AND GRANTEE = '<SAP_DB_USER>';6
If permissions are missing, grant the required privileges to the SAP S/4HANA database user.
GRANT SELECT ON "YOUR_SCHEMA"."YOUR_TABLE_OR_VIEW" TO "<SAP_DB_USER>";7
After ensuring the object exists and has correct permissions, re-run the process that caused the error.
3. Reactivate and Replicate Data Source Metadata easy
A common quick fix that refreshes the metadata associated with the data source.
1
Access the SAP S/4HANA system via SAP GUI.
2
Navigate to transaction code `RSA1` (BW Modeling Workbench) or the relevant data modeling transaction.
3
Locate the data source that is causing the error.
4
Right-click on the data source and select 'Reactivate'.
5
If the data source is from an external system or requires replication (e.g., for ODP contexts), navigate to the 'Source Systems' or 'Data Sources' tree, right-click on the relevant source system or data source, and select 'Replicate Metadata'.
6
Monitor the replication process to ensure it completes without errors.
7
Once reactivation and replication are successful, re-run the process that triggered the error.
