Description

This error signifies that an SQL operation attempted to use an index name that either does not exist or is incorrectly referenced within the database. It commonly arises during data manipulation, custom report execution, or schema management tasks in SAP S/4HANA.

Error Message

ERR_SQL_INV_INDEX

🔍

Known Causes

4 known causes

⚠️

Typo or Misspelling

The index name specified in the SQL statement, application code, or configuration contains a typographical error or misspelling, preventing the database from locating it.

⚠️

Non-Existent Index

The referenced index has either been dropped, was never created, or does not exist within the current database schema context.

⚠️

Incorrect Database Schema

The operation is attempting to access an index that exists in a different database schema than the one currently active or explicitly specified.

⚠️

Case Sensitivity Mismatch

The database system enforces case sensitivity for object names, and the provided index name does not match the actual case of the existing index.

Solutions

3 solutions available

1. Identify and Correct Invalid Index Name in SQL Statement easy

Locate the SQL statement causing the error and correct the misspelled or incorrectly formatted index name.

1

Analyze the SAP S/4HANA application logs or traces to pinpoint the exact SQL statement that is failing with error 261.

Example: Look for ST05 (SQL Trace) or SM21 (System Log) for the specific transaction or program.

2

Within the identified SQL statement, carefully examine all references to index names. Index names in SAP HANA can be case-sensitive and have specific naming conventions (e.g., often prefixed with 'IDX_', 'IX_', or related to the table name).

Example of a potentially incorrect index reference: `SELECT * FROM MYTABLE USE INDEX (MY_INEX)` (if the index is actually `MY_INDEX`)

3

Compare the index name used in the SQL statement with the actual index names defined for the relevant table in the SAP HANA database. You can use the SAP HANA Studio or SQL Console for this.

SELECT INDEX_NAME FROM "SYS_TABLES"."INDEXES" WHERE TABLE_NAME = 'MYTABLE';

4

Correct the index name in the SQL statement to match the exact, case-sensitive name found in the database schema. If the SQL statement is part of custom ABAP code, this correction needs to be made in the ABAP program. If it's part of SAP standard code, a SAP Note or patch might be required.

Example of corrected statement: `SELECT * FROM MYTABLE USE INDEX (MY_INDEX)`

2. Verify Index Existence and Schema Ownership medium

Ensure the index exists and is accessible within the correct schema when referenced.

1

Using SAP HANA Studio or a SQL client, query the system views to confirm the existence of the index and its associated table.

SELECT a.TABLE_NAME, a.INDEX_NAME, b.SCHEMA_NAME FROM "SYS_TABLES"."INDEXES" a JOIN "SYS_TABLES"."TABLES" b ON a.TABLE_ID = b.TABLE_ID WHERE a.INDEX_NAME = 'INVALID_INDEX_NAME';

2

If the index is not found, it might have been dropped, renamed, or never created. Investigate the database history or application configuration.

3

If the index exists but the SQL statement is failing, ensure that the user executing the statement has the necessary privileges to access the index and its underlying table, and that the index is in the same schema or appropriately qualified in the query.

Example: If the index is in schema 'SCHEMA_A' and the table is in 'SCHEMA_B', the query might need to be `SELECT * FROM SCHEMA_B.MYTABLE USE INDEX (SCHEMA_A.MY_INDEX)` (syntax might vary).

4

If the index is missing and required, consider recreating it using the appropriate DDL statement. This should be done with caution and after thorough impact analysis, potentially involving SAP support.

CREATE INDEX "MY_INDEX" ON "MYTABLE" ("COLUMN1", "COLUMN2");

3. Rebuild or Regenerate Index advanced

In rare cases, index corruption or inconsistencies can lead to invalid name errors. Rebuilding the index can resolve this.

1

Identify the specific index that is causing the error and its associated table.

text

2

Perform a backup of the relevant table and its indexes before proceeding. This is crucial for recovery in case of any issues.

text

3

Use the SAP HANA Studio or SQL Console to drop and then recreate the index. This process effectively rebuilds the index.

DROP INDEX "INVALID_INDEX_NAME";
CREATE INDEX "CORRECT_INDEX_NAME" ON "MYTABLE" ("COLUMN1", "COLUMN2");

4

Alternatively, if the index is a system-managed index or part of a specific SAP S/4HANA feature, consult SAP Notes for specific procedures to regenerate or re-index the table. This might involve specific SAP transaction codes or administrative tools.

Example: For certain materialized views or calculation views, regeneration might be a different process.

5

After rebuilding, re-test the application functionality that previously failed.
