Solutions

3 solutions available

1. Identify and Drop Duplicate Trigger medium

Locate and remove the pre-existing trigger with the same name.

1

Connect to your SAP HANA database using a SQL client (e.g., SAP HANA Studio, hdbsql).

2

Execute a query to list all existing triggers and their associated schemas and tables. You are looking for triggers with the same name as the one you are trying to create.

SELECT TRIGGER_NAME, SCHEMA_NAME, TABLE_NAME FROM TRIGGERS WHERE TRIGGER_NAME = '<YOUR_TRIGGER_NAME>';

3

If the query returns a result, a trigger with that name already exists. You will need to drop the existing trigger. **Caution:** Ensure this is not a critical system trigger before proceeding.

DROP TRIGGER "<SCHEMA_NAME>"."<YOUR_TRIGGER_NAME>";

4

After dropping the duplicate trigger, attempt to create your new trigger again.

2. Rename the New Trigger easy

Assign a unique name to the trigger being created.

1

Review the trigger definition you are attempting to create. Identify the `CREATE TRIGGER` statement and the trigger name specified.

CREATE TRIGGER "<YOUR_TRIGGER_NAME>" ...

2

Choose a new, unique name for your trigger. It's good practice to include a prefix or suffix that indicates the purpose or origin of the trigger (e.g., Z_MY_TRIGGER, MY_TRIGGER_CUSTOM).

3

Modify the `CREATE TRIGGER` statement to use the new, unique name.

CREATE TRIGGER "<NEW_UNIQUE_TRIGGER_NAME>" ...

4

Execute the modified `CREATE TRIGGER` statement.

3. Investigate Custom Code or Add-Ons advanced

Determine if the duplicate trigger originates from custom developments or installed add-ons.

1

Consult with your SAP development team or functional consultants responsible for custom developments and any installed SAP add-ons or third-party solutions.

2

Request them to review their code and configurations for any existing triggers that might be using the same name.

3

If a duplicate trigger is found within custom code or an add-on, coordinate with the responsible team to either: a) remove the redundant trigger, or b) rename the trigger in their development.

4

Once the conflict is resolved by the responsible team, attempt to create your trigger again.
