SAP S/4HANA Error 502: Invalid SQL Task Name
Description
The ERR_SQL_INV_TASK error indicates that an SQL operation within SAP S/4HANA attempted to reference a database task (e.g., a stored procedure, function, or scheduled job) by a name that is not recognized or does not exist. This error typically occurs during the execution of custom reports, integrations, or background processes that interact directly with the underlying database.
Error Message
ERR_SQL_INV_TASK
Known Causes
4 known causesIncorrect Task Name Reference
The SQL statement, custom code, or application configuration contains a typo or an incorrect name for the intended database task.
Missing Database Task
The referenced task has been deleted, renamed, or was never created in the database schema that the SAP S/4HANA system is attempting to access.
Wrong Database Schema/Context
The SQL operation is executed under a database schema or user context where the specified task is not available or visible due to permissions or configuration.
Incomplete Deployment
During a system migration, upgrade, or deployment, the necessary database tasks were not fully or correctly deployed to the target environment.
Solutions
3 solutions available1. Validate and Correct SQL Task Definition easy
Ensures the SQL task name in the program or configuration is valid and correctly spelled.
1
Identify the program or configuration where the SQL task is being called or defined. This could be within ABAP code, a custom report, a CDS view, or a system configuration parameter.
2
Locate the specific SQL task name that is causing the error. It's often a literal string or a variable holding the task name.
3
Verify the spelling and syntax of the SQL task name against the actual definition of the task. Ensure there are no typos, extra spaces, or incorrect characters. SQL task names are typically case-sensitive.
4
If the SQL task is defined in ABAP, review the `CALL FUNCTION` or `CALL METHOD` statements that invoke SQL tasks. For example, ensure the parameter for the task name is correctly populated.
ABAP
DATA lv_task_name TYPE string VALUE 'YOUR_CORRECT_TASK_NAME'.
CALL FUNCTION 'SQL_TASK_EXECUTE'
EXPORTING
iv_task_name = lv_task_name
IMPORTING
...
EXCEPTIONS
... .5
If the SQL task is part of a CDS view or another data definition, check the syntax for referencing the task.
6
Save and activate the corrected program or configuration. Then, re-run the operation that triggered the error.
2. Check SAP HANA SQL Task Authorization medium
Confirms that the user or application executing the SQL task has the necessary privileges to access and execute it.
1
Identify the user or technical user (e.g., RFC user, application user) that is executing the S/4HANA process leading to the SQL error.
2
Access SAP HANA Studio or SAP HANA Cockpit to manage user roles and privileges.
3
Navigate to the SQL task's schema and locate the SQL task object. You can typically find this under the 'Content' or 'Development' section, within the relevant schema.
4
Review the privileges granted to the user or role associated with the executing user. Ensure they have at least `EXECUTE` privilege on the specific SQL task.
SQL (HANA)
SELECT * FROM granted_privileges WHERE GRANTEE = '<USER_OR_ROLE_NAME>' AND OBJECT_NAME = '<SCHEMA_NAME>.<SQL_TASK_NAME>' AND PRIVILEGE_TYPE = 'EXECUTE';5
If the privilege is missing, grant the `EXECUTE` privilege to the user or role. It's recommended to grant privileges to roles rather than directly to users for better manageability.
SQL (HANA)
GRANT EXECUTE ON '<SCHEMA_NAME>.<SQL_TASK_NAME>' TO <USER_OR_ROLE_NAME>;6
Commit the changes and re-run the S/4HANA operation. For security best practices, grant only the minimum necessary privileges.
3. Inspect SAP HANA SQL Task Metadata advanced
Verifies the integrity and existence of the SQL task definition in the SAP HANA database.
1
Connect to the SAP HANA database using SAP HANA Studio or a database client (e.g., hdbsql).
2
Query the system views to check if the SQL task actually exists and is correctly registered in the database catalog. The error `ERR_SQL_INV_TASK` strongly suggests the task itself is not found or is malformed.
SQL (HANA)
SELECT * FROM "SYS"."OBJECTS"
WHERE SCHEMA_NAME = '<SCHEMA_NAME>' AND OBJECT_NAME = '<SQL_TASK_NAME>' AND OBJECT_TYPE = 'SQL_TASK';3
If the SQL task is not found or its metadata appears corrupted, you may need to re-create or re-deploy the SQL task. This often involves using SAP HANA development tools (like SAP Business Application Studio or Eclipse with HANA plugins) to build and deploy the task.
4
If the SQL task was recently created or modified, ensure the deployment process completed successfully and without errors. Check deployment logs for any issues.
5
If the SQL task is part of an SAP-delivered object, consider checking for SAP Notes or consulting SAP Support. It might indicate a bug or a missing patch.
