SAP S/4HANA Error 465: Failed SQL Trigger Execution
Description
Error 465, 'ERR_SQL_INV_USABLE_TRIGGER - Cannot execute trigger', indicates that an automated database action, known as a trigger, failed to complete during an operation. This typically occurs when SAP S/4HANA attempts to perform a data manipulation language (DML) operation (like INSERT, UPDATE, DELETE) that invokes a database trigger, but the trigger itself cannot be executed for various reasons.
Error Message
ERR_SQL_INV_USABLE_TRIGGER - Cannot execute trigger
Known Causes
4 known causesDisabled or Invalid Trigger
The database trigger intended to execute might be disabled, or its definition could be syntactically incorrect or logically flawed.
Insufficient User Permissions
The database user account initiating the operation lacks the necessary privileges to execute or interact with the specific database trigger.
Underlying Database Issue
Problems within the database system itself, such as resource contention, corruption, or unexpected behavior, can prevent trigger execution.
Trigger Logic Error
The code or logic embedded within the trigger contains an error that causes it to fail when attempting to execute.
Solutions
3 solutions available1. Review and Recompile Database Triggers medium
Identifies and recompiles potentially invalid database triggers that are causing the error.
1
Connect to the SAP HANA database using a privileged user (e.g., SYSTEM).
2
Query the system view `TRIGGERS` to identify triggers that are marked as invalid.
SELECT SCHEMA_NAME, TRIGGER_NAME, STATUS FROM TRIGGERS WHERE STATUS = 'INVALID';3
For each invalid trigger identified, attempt to recompile it. If the trigger is associated with a specific table, you can often recompile it by modifying and saving the table definition in SAP HANA Studio or via SQL.
ALTER TRIGGER "<schema_name>"."<trigger_name>" RECOMPILE;4
If recompilation fails, examine the trigger's source code for syntax errors, incorrect object references, or logical flaws. Correct any identified issues.
5
After correcting the trigger code, recompile it using the `ALTER TRIGGER ... RECOMPILE` statement.
6
Test the functionality that previously triggered error 465 to confirm the issue is resolved.
2. Investigate Trigger Dependencies and Object Validity advanced
Checks for issues with objects that the trigger relies on, which could be causing its failure.
1
Identify the specific trigger that is failing. This might be evident from the application logs or by correlating error timestamps with trigger execution times.
2
Examine the trigger's definition to understand which other database objects (tables, views, procedures, functions) it interacts with.
SELECT TRIGGER_DEFINITION FROM TRIGGERS WHERE SCHEMA_NAME = '<schema_name>' AND TRIGGER_NAME = '<trigger_name>';3
Verify the existence and validity of all referenced objects. Check their status in the SAP HANA system views like `TABLES`, `VIEWS`, `PROCEDURES`, and `FUNCTIONS`.
SELECT SCHEMA_NAME, OBJECT_NAME, OBJECT_TYPE, STATUS FROM VIEWS WHERE SCHEMA_NAME = '<schema_name>' AND OBJECT_NAME IN ('<referenced_object1>', '<referenced_object2>');4
If any dependent objects are invalid, address those issues first (e.g., recompile procedures, correct table definitions).
5
Once dependent objects are valid, recompile the failing trigger.
ALTER TRIGGER "<schema_name>"."<trigger_name>" RECOMPILE;6
Perform a test to ensure the trigger now executes successfully.
3. Check for Runtime Errors within Trigger Logic advanced
Analyzes the trigger's execution path for runtime errors that might not be captured by a simple invalid status.
1
Enable detailed logging for database operations or specifically for trigger execution if your SAP HANA version and configuration support it. This might involve `AUDIT` settings or trace configurations.
2
Reproduce the scenario that causes error 465. Analyze the database traces or logs generated during this reproduction.
3
Look for specific SQL error messages or exceptions that occur during the trigger's execution. These might provide more granular information than ERR_SQL_INV_USABLE_TRIGGER.
4
If a runtime error is identified (e.g., division by zero, data type mismatch, constraint violation), debug the trigger's logic to handle these conditions gracefully. This might involve adding error handling blocks (`TRY...CATCH` if supported by the trigger language) or input validation.
5
Modify the trigger code to address the identified runtime error and then recompile it.
6
Test the fix by re-executing the problematic scenario.
