SAP S/4HANA Error 434: Invalid Database Object Reference

📦 SAP S/4HANA

📋

Description

This error indicates that an SAP S/4HANA operation attempted to access a database object (such as a table, view, or stored procedure) that could not be found or accessed by its specified ID. It commonly occurs during data retrieval, report generation, or custom application execution when the underlying database structure is referenced incorrectly or is missing.

Error Message

ERR_SQL_INV_OBJECT

🔍

Known Causes

4 known causes

⚠️

Missing or Deleted Database Object

The specific database object (e.g., table, view, index) that the system is attempting to access has been deleted from the database or was never created.

⚠️

Incorrect Object Reference

The application code, custom report, or configuration is referencing a database object using an incorrect name, ID, or schema qualifier.

⚠️

Insufficient User Permissions

The user account or system process attempting to access the database object lacks the necessary privileges (e.g., SELECT, EXECUTE) on that object.

⚠️

Database Schema Inconsistency

There is a mismatch between the expected database schema definition by SAP S/4HANA and the actual objects present, often due to incomplete upgrades or manual database changes.

Solutions

3 solutions available

1. Verify and Recreate Missing or Corrupted Database Objects medium

This solution focuses on identifying and restoring any database objects that are missing or corrupted, which is a common cause of ERR_SQL_INV_OBJECT.

Identify the specific database object causing the error. This often requires analyzing the SAP application logs (e.g., SM21, ST22) for more detailed error messages that pinpoint the table, view, or other object.

Access the SAP HANA database using a privileged user (e.g., SYSTEM) via SAP HANA Studio or hdbsql.

Check for the existence of the identified object. For example, to check for a table named 'MY_TABLE' in schema 'MY_SCHEMA':

SELECT * FROM SYS.TABLES WHERE SCHEMA_NAME = 'MY_SCHEMA' AND TABLE_NAME = 'MY_TABLE';

If the object is missing, determine the correct definition. This can be found in SAP's installation guides, transport requests, or by comparing with a healthy system. In some cases, SAP Notes might provide SQL scripts to recreate standard objects.

If the object exists but appears corrupted (e.g., invalid structure, missing columns), consider dropping and recreating it. **Caution: This is a destructive operation and should only be performed after thorough analysis and with proper backups.**

DROP TABLE "MY_SCHEMA"."MY_TABLE";

Recreate the object using the correct SQL definition. For example, for a table:

CREATE COLUMN TABLE "MY_SCHEMA"."MY_TABLE" (
    "COLUMN1" NVARCHAR(50) NOT NULL,
    "COLUMN2" INTEGER
);
-- Add primary keys, indexes, etc. as per the original definition.

Grant necessary privileges to SAP users or roles that require access to the recreated object.

GRANT SELECT ON "MY_SCHEMA"."MY_TABLE" TO "<SAP_USER_ROLE>";

Restart the relevant SAP application instances or services that utilize the affected object to pick up the changes.

2. Correct Invalid Object Status in SAP HANA easy

This solution addresses scenarios where database objects are marked as invalid within SAP HANA, preventing their use.

Connect to the SAP HANA database using SAP HANA Studio or hdbsql.

Query the system views to identify invalid objects. Look for objects with a status other than 'VALID'. For example, to check for invalid tables:

SELECT SCHEMA_NAME, TABLE_NAME, VALID FROM SYS.TABLES WHERE VALID = 'FALSE';

For invalid views, stored procedures, or functions, use the following queries:

SELECT SCHEMA_NAME, VIEW_NAME, VALID FROM SYS.VIEWS WHERE VALID = 'FALSE';
SELECT SCHEMA_NAME, PROCEDURE_NAME, VALID FROM SYS.PROCEDURES WHERE VALID = 'FALSE';
SELECT SCHEMA_NAME, FUNCTION_NAME, VALID FROM SYS.FUNCTIONS WHERE VALID = 'FALSE';

Attempt to recompile the invalid objects. For tables, this might involve altering them slightly (e.g., adding a comment) or recreating them if the issue is more severe (refer to Solution 1). For views, stored procedures, and functions, you can often recompile them using the ALTER statement.

ALTER VIEW "MY_SCHEMA"."MY_VIEW" RECOMPILE;
ALTER PROCEDURE "MY_SCHEMA"."MY_PROCEDURE" RECOMPILE;
ALTER FUNCTION "MY_SCHEMA"."MY_FUNCTION" RECOMPILE;

If recompilation doesn't resolve the issue, investigate the dependencies of the invalid object. An invalid object might be dependent on another invalid object.

After attempting to fix invalid objects, restart the relevant SAP application instances or services.

3. Review and Correct Schema and Object Naming Conventions easy

This solution addresses potential issues arising from incorrect schema or object names, case sensitivity, or the use of reserved keywords.

Carefully examine the SAP application logs (SM21, ST22) to confirm the exact schema and object name being referenced in the error message.

Connect to the SAP HANA database using SAP HANA Studio or hdbsql.

Verify the case sensitivity of object names. SAP HANA is case-sensitive by default for object names unless they are enclosed in double quotes during creation. Ensure that the application is referencing the object with the correct casing.

Check if the schema name and object name are correctly specified in the application's configuration or the SQL statements being executed.

If the object name is a reserved keyword in SAP HANA SQL, it must be enclosed in double quotes (e.g., `"SELECT"` instead of `SELECT`).

If the object was created with double quotes, it must always be referenced with double quotes and the exact casing.

If a naming convention mismatch is found, update the application configuration or the SQL statements to use the correct schema and object name with the appropriate casing and quoting.

Restart the relevant SAP application instances or services.
