Description

This error indicates that an attempt was made to create a data statistics object, but an object with the same identifier already exists in the SAP S/4HANA system. It typically occurs during database maintenance, system upgrades, or when re-generating performance-related statistics.

Known Causes

3 known causes

⚠️

Duplicate Creation Attempt

You tried to create a data statistics object with an identifier that is already in use within the system.

⚠️

Incomplete Prior Cleanup

A previous operation to delete or re-create the statistics object did not fully complete, leaving conflicting remnants.

⚠️

Manual Configuration Conflict

Custom scripts or direct database commands attempted to create statistics without checking for existing objects.

Solutions

3 solutions available

1. Drop and Recreate the Statistics Object easy

Removes the existing statistics object and creates a new one for the specified table.

1

Identify the table for which the statistics object is causing the error. This information is usually available in the surrounding error messages or logs.

2

Connect to the SAP HANA database using a SQL client (e.g., SAP HANA Studio, DBeaver, or a command-line tool).

3

Execute the following SQL command to drop the existing statistics object. Replace `<schema_name>` with the actual schema name and `<table_name>` with the table name. The statistics object name is typically derived from the table name, often with a suffix like `_STAT`.

DROP STATISTICS <schema_name>.<table_name>_STAT;

4

Execute the following SQL command to create a new statistics object for the table. This command will automatically generate a statistics object if one doesn't exist. Replace `<schema_name>` and `<table_name>` accordingly.

CREATE STATISTICS <schema_name>.<table_name>;

5

Verify that the statistics object has been created successfully by querying the system views.

SELECT * FROM SYS.STATISTICS WHERE TABLE_NAME = '<table_name>' AND SCHEMA_NAME = '<schema_name>';

2. Update Existing Statistics Object medium

Updates the definition of the existing statistics object, effectively resolving the conflict.

1

Identify the table and the existing statistics object causing the error. This often involves inspecting system views.

2

Connect to the SAP HANA database using a SQL client.

3

Query the `SYS.STATISTICS` system view to get details about the existing statistics object. You'll need the `SCHEMA_NAME`, `TABLE_NAME`, and `STATISTICS_OBJECT_NAME`.

SELECT SCHEMA_NAME, TABLE_NAME, STATISTICS_OBJECT_NAME FROM SYS.STATISTICS WHERE TABLE_NAME = '<table_name>' AND SCHEMA_NAME = '<schema_name>';

4

Use the `ALTER STATISTICS` statement to update the existing statistics object. This can involve redefining columns or properties. If you are unsure of the exact definition, consider dropping and recreating as in the first solution.

ALTER STATISTICS <schema_name>.<statistics_object_name> ALTER COLUMN <column_name> WITH OPTIONS (SAMPLE_SIZE 10000);

5

Alternatively, if the issue is with the auto-generated statistics object name, you might need to drop it and then explicitly create one with a different name if the system continues to attempt to create a duplicate. The safest approach is often to drop and recreate.

DROP STATISTICS <schema_name>.<statistics_object_name>;
CREATE STATISTICS <schema_name>.<table_name> ON <schema_name>.<table_name> (<column_name1>, <column_name2>);

6

Verify the changes by querying `SYS.STATISTICS` again.

SELECT * FROM SYS.STATISTICS WHERE TABLE_NAME = '<table_name>' AND SCHEMA_NAME = '<schema_name>';

3. Investigate and Resolve Underlying Process Conflict advanced

Determines which process is attempting to create the statistics object and resolves the conflict.

1

Identify the exact moment the error occurs. This is crucial for correlating with system activities.

2

Review SAP S/4HANA application logs and SAP HANA trace files for any processes that might be attempting to create or manage statistics for the affected table. Look for keywords like 'CREATE STATISTICS', 'STATISTICS', or the table name.

3

If the error occurs during a specific SAP transaction or background job, investigate the configuration and execution of that process. It might be attempting to create statistics when they are already managed by another mechanism (e.g., automatic statistics collection).

4

Check the SAP HANA `SYS.STATISTICS` system view to see if a statistics object already exists for the table. If it does, the conflicting process might be unaware of its existence.

SELECT * FROM SYS.STATISTICS WHERE TABLE_NAME = '<table_name>' AND SCHEMA_NAME = '<schema_name>';

5

If the conflict is with SAP's automatic statistics collection, you might need to adjust the configuration for that specific table or globally. This can often be done via transaction `ST04` (Database Performance) or specific HANA Studio configurations.

6

If a custom application or script is causing the conflict, modify that code to check for the existence of the statistics object before attempting to create it.

-- Example pseudo-code
IF NOT EXISTS (SELECT 1 FROM SYS.STATISTICS WHERE TABLE_NAME = 'MY_TABLE' AND SCHEMA_NAME = 'MY_SCHEMA') THEN
  CREATE STATISTICS MY_SCHEMA.MY_TABLE;
END IF;

7

Consult SAP Notes and SAP Support if the origin of the conflicting process is unclear or if standard resolution steps do not apply.
