SAP S/4HANA Error 445: Invalid Trigger Name
Description
This error indicates that an operation attempted to reference a database trigger using a name that is either misspelled, incorrect, or does not exist within the specified database schema in SAP S/4HANA. It typically occurs during custom development, configuration, or data migration activities involving database triggers.
Error Message
ERR_SQL_INV_TRIGGER
Known Causes
3 known causesIncorrect Trigger Name
The specified trigger name contains a typo or does not match the exact name of an existing database trigger.
Trigger Does Not Exist
The database trigger referenced by the operation has not been created or is missing from the database schema.
Wrong Database Schema
The trigger name is valid, but it is being looked for in an incorrect or unintended database schema.
Solutions
3 solutions available1. Verify Trigger Name in Custom Code easy
Check and correct trigger names used in custom ABAP or SQL code.
1
Identify the ABAP program or SQL script that is attempting to create or reference a trigger.
2
Examine the trigger definition or usage within the code. Look for any typographical errors, incorrect characters, or excessively long trigger names.
Example of incorrect trigger name (hypothetical):
CREATE TRIGGER my_trigger_name_too_long_12345678901234567890 ON my_table FOR EACH ROW BEGIN ... END;
Example of correct trigger name:
CREATE TRIGGER my_trigger_name_short ON my_table FOR EACH ROW BEGIN ... END;3
Ensure the trigger name adheres to the database's naming conventions (e.g., maximum length, allowed characters). For SAP HANA, trigger names should be valid identifiers and generally not exceed 30 characters.
4
Correct any invalid trigger names in the source code and re-deploy or re-execute the code.
2. Review SAP Standard Object Triggers medium
Investigate if the error originates from a modification or enhancement of SAP standard objects.
1
Use transaction SE80 to navigate to the relevant SAP standard object (e.g., program, function module, table) that might be related to the error.
2
Look for any custom enhancements (e.g., BADIs, user exits, enhancement spots) that might be attempting to create or manipulate triggers.
3
If enhancements are found, examine the code within those enhancements for incorrect trigger names. Pay close attention to syntax and naming conventions.
4
If a custom trigger is being created via an enhancement, ensure it follows SAP HANA naming best practices and doesn't conflict with existing or intended standard triggers.
5
If the error points to a standard SAP trigger that has been inadvertently modified or corrupted (highly unlikely in standard deployment), a SAP Note or a system refresh might be necessary. Consult SAP Support.
3. Database Trigger Definition Validation (SAP HANA) advanced
Directly check and correct invalid trigger names in the SAP HANA database catalog.
1
Connect to the SAP HANA database using a SQL client (e.g., SAP HANA Studio, hdbsql).
2
Query the system views to identify triggers and their associated objects.
SELECT TRIGGER_NAME, TABLE_NAME, SCHEMA_NAME FROM SYS.TRIGGERS;
SELECT TRIGGER_NAME, SCHEMA_NAME, TRIGGER_DEFINITION FROM SYS.TRIGGERS WHERE TRIGGER_NAME = 'YOUR_POTENTIALLY_INVALID_TRIGGER_NAME';3
If the error message provides a specific trigger name, search for it in the `SYS.TRIGGERS` catalog view. If the name itself is invalid, you may need to drop and recreate the trigger with a valid name.
DROP TRIGGER "YOUR_INVALID_TRIGGER_NAME";
CREATE TRIGGER "YOUR_VALID_TRIGGER_NAME" AFTER INSERT ON "YOUR_TABLE" FOR EACH ROW BEGIN ... END;4
Ensure trigger names comply with SAP HANA identifier rules: start with a letter, can contain letters, numbers, and underscores, and are case-sensitive if quoted. Avoid special characters and excessively long names (typically up to 30 characters).
5
If the invalid trigger name is part of a stored procedure or function, you'll need to modify that stored procedure/function definition to use a valid trigger name.
