SAP S/4HANA Error 651: Existing Object Name Conflict
Description
This error occurs in SAP S/4HANA when attempting to create a new database object, such as a table, view, or index, using a name that is already in use within the database schema. It indicates a conflict where the system prevents the creation of duplicate object identifiers to maintain data integrity and system consistency.
Error Message
ERR_SQL_EXST_OBJECT
Known Causes
3 known causesManual Object Creation Attempt
A user manually tries to create a database object (e.g., table, view, index) using a name that is already defined in the current database schema.
Automated Script Conflict
An automated script, program, or a transport request attempts to create an object with a name that already exists, often due to an oversight in checking for pre-existing objects.
Migration or Update Overlap
During data migration, system upgrades, or installation of add-ons, a process attempts to create an object with a name that conflicts with an existing one.
Solutions
3 solutions available1. Identify and Rename Conflicting Object medium
Locate the object causing the name conflict and rename it to resolve the error.
1
Identify the object name that is causing the conflict. This is usually evident from the context of the operation that triggered the error (e.g., during a transport import, system upgrade, or custom development). The error message itself might provide clues or you may need to consult the relevant logs (e.g., STMS import logs, SAP application logs).
2
Connect to the target SAP system using a tool like SAP HANA Studio or `hdbsql`.
3
Query the system catalog to find the existing object with the conflicting name. Replace `[CONFLICTING_OBJECT_NAME]` with the actual name.
SELECT * FROM SYS.OBJECTS WHERE OBJECT_NAME = '[CONFLICTING_OBJECT_NAME]';
SELECT * FROM SYS.TABLES WHERE TABLE_NAME = '[CONFLICTING_OBJECT_NAME]';
SELECT * FROM SYS.VIEWS WHERE VIEW_NAME = '[CONFLICTING_OBJECT_NAME]';
SELECT * FROM SYS.PROCEDURES WHERE PROCEDURE_NAME = '[CONFLICTING_OBJECT_NAME]';4
If the object is a custom object and not a critical system object, decide on a new, unique name. If it's a standard SAP object that has been inadvertently created with a duplicate name (less common, but possible due to errors), consult SAP Notes and potentially SAP support.
5
Rename the existing object. This requires appropriate privileges. The exact syntax for renaming depends on the object type. For tables, views, or procedures, you can use the `RENAME OBJECT` command. Be extremely cautious when renaming standard SAP objects. For custom objects, this is a more straightforward operation.
RENAME OBJECT '[EXISTING_SCHEMA_NAME]'. '[CONFLICTING_OBJECT_NAME]' TO '[NEW_UNIQUE_OBJECT_NAME]';6
Retry the operation that initially failed. If the object was a custom object, ensure that any application code or configuration referencing the old name is updated to reflect the new name.
2. Verify Transport Import Dependencies medium
Ensure that all dependent objects are imported correctly before attempting to import the object causing the conflict.
1
When importing transports into SAP S/4HANA, object name conflicts often arise if dependent objects have not been imported or if there are inconsistencies in the transport queue.
2
In transaction STMS, check the import queue for the target system. Examine the import logs for any previous errors or warnings related to the object or its dependencies.
3
Identify the specific object that is causing the 'Existing Object Name Conflict' error (ERR_SQL_EXST_OBJECT).
4
If the conflict is with a table, view, or procedure, check if a newer version or a related object from another transport is already present. You might need to import prerequisite transports first.
5
If the conflict is with a Data Dictionary object (e.g., DDIC object), ensure that all related DDIC objects are in the correct state and order of import. Sometimes, a change to a DDIC object might be in a transport that hasn't been fully processed.
6
If the object is a custom development, review the transport history. It's possible that the object was created or modified in a previous transport that encountered issues or was not fully imported.
7
If necessary, re-import any prerequisite transports or ensure that all objects in the current transport are imported in the correct order. Sometimes, a full system consistency check might be required.
8
Once dependencies are resolved, re-attempt the import of the transport that caused the error.
3. Review and Correct Custom Development medium
Address naming conflicts introduced by custom-developed objects.
1
This error is common when developing custom objects (e.g., tables, views, procedures, functions) in SAP S/4HANA that accidentally reuse an existing object name, either a standard SAP object or another custom object.
2
Identify the custom development project or transport that is triggering the error.
3
Examine the Data Dictionary (SE11) or ABAP Development Tools (ADT) for the objects being created or modified. Pay close attention to the names being assigned.
4
Before creating a new object, perform a search in SE11 (or ADT) to ensure the intended name is not already in use. Use wildcards if necessary, but be precise.
5
If a conflict is found, rename the custom object to a unique name. Follow naming conventions for custom objects (e.g., using a customer namespace like 'Z' or 'Y').
6
If the conflicting object is a standard SAP object that your custom development is meant to interact with, you may need to adjust your development to use the correct API or reference the object indirectly, rather than trying to create a duplicate.
7
After renaming the custom object, update any related ABAP code, configuration, or other objects that reference the old name.
8
Re-activate and re-generate the custom development objects, and then retry the operation that caused the error.
