SAP S/4HANA Error 472: Duplicate Data Source Name
Description
This error indicates an attempt to create or configure a data source using a name that is already registered within your SAP S/4HANA system. It typically occurs during data integration setup, system configuration, or data migration activities when a unique identifier is required but a conflict is detected.
Error Message
ERR_SQL_EXST_DATA_SOURCE: Cannot use duplicate data source name
Known Causes
4 known causesManual Configuration Error
A user manually entered a data source name that is already in use, leading to a direct naming conflict during the creation process.
Automated Script Duplication
An automated script, program, or configuration task attempted to create a data source with a name that already exists within the system.
Data Migration Conflict
During a data migration or system replication, a data source with an identical name was attempted to be imported into an environment where it already exists.
Unverified Name Reuse
A previously used or deprecated data source name was inadvertently selected or re-entered without confirming its current status or existence.
Solutions
3 solutions available1. Identify and Remove Duplicate Data Source Entries medium
Locate and delete redundant data source definitions within the SAP S/4HANA system.
1
Access the SAP S/4HANA system using an administrator role (e.g., SAP_ALL or equivalent).
2
Navigate to the transaction code responsible for managing data sources. This is typically `RSA1` (BW Modeling) or related transactions for specific data source types in S/4HANA (e.g., CDS views, OData services). The exact transaction might vary based on the specific context of the error.
3
Search for the data source name mentioned in the error message. Use the search functionalities within the relevant transaction to find all instances of this name.
4
Carefully review the search results to identify duplicate entries. These duplicates might be in different versions, development/production clients, or simply erroneous entries.
5
Delete the duplicate data source entries. Ensure you are deleting the correct, non-production or redundant entry. **Caution:** Deleting the wrong data source can impact reporting and processes.
6
Save your changes and retry the operation that triggered the error.
2. Rename or Recreate the Data Source medium
Modify the name of the conflicting data source or create a new one with a unique identifier.
1
Identify the data source causing the conflict, as per the error message.
2
Determine if the existing data source is actively used and critical. If not, consider renaming it to a unique identifier.
3
In the relevant SAP S/4HANA transaction (e.g., `RSA1`, or transaction for CDS view/OData service management), locate the data source.
4
Use the 'Rename' or equivalent functionality to assign a new, unique name. Ensure the new name adheres to naming conventions.
5
If renaming is not feasible or if the data source is corrupt, consider creating a new data source with a distinct name and copying the configuration/logic from the old one.
6
Update any references or applications that use the old data source name to point to the new name.
7
Save changes and re-execute the operation.
3. Check and Adjust Data Dictionary Definitions advanced
Verify and correct underlying data dictionary objects if the duplicate name arises from a lower-level definition.
1
This solution applies if the 'data source name' refers to an underlying database object or metadata that has a duplicate definition.
2
Connect to the SAP HANA database directly using a database client (e.g., SAP HANA Studio, hdbsql).
3
Execute SQL queries to check for duplicate object names in the relevant schema. The exact schema will depend on the type of data source (e.g., `_SYS_BIC` for CDS views, or custom schemas for other objects).
SELECT SCHEMA_NAME, OBJECT_NAME, COUNT(*) FROM "SYS"."OBJECTS" WHERE OBJECT_NAME = '<DUPLICATE_DATA_SOURCE_NAME>' GROUP BY SCHEMA_NAME, OBJECT_NAME HAVING COUNT(*) > 1;4
If duplicates are found, investigate the purpose and origin of each duplicate object. This may involve examining object creation logs or metadata.
5
Based on the investigation, decide which duplicate object to rename or delete. **Extreme caution is advised** as direct database manipulation can have severe consequences.
6
Use `ALTER TABLE` or `ALTER VIEW` statements to rename the duplicate object, or `DROP` statement to remove it. This should ideally be done in coordination with SAP support or experienced database administrators.
ALTER TABLE "<SCHEMA_NAME>"."<DUPLICATE_OBJECT_NAME>" RENAME TO "<NEW_UNIQUE_OBJECT_NAME>";7
After making changes at the database level, synchronize these changes within the SAP S/4HANA application layer. This might involve reactivating or re-transporting relevant objects.
