Duplicate Credential Creation Attempt

This error most commonly occurs when a user or an automated process attempts to create a SQL credential with a name or identifier that is already in use by an existing credential.

⚠️

Misconfiguration During Setup

Incorrect parameters or settings during the initial setup or integration of SAP S/4HANA components can lead to an attempt to provision an already existing credential.

Solutions

3 solutions available

1. Remove Duplicate SQL Credential Entry easy

Identify and delete the existing SQL credential that is causing the conflict.

1

Connect to your SAP HANA database using a tool like SAP HANA Studio or hdbsql.

2

Query the system view `_SYS_REPO.CREDENTIALS` to find existing credentials with the same name as the one you are trying to create.

SELECT * FROM "_SYS_REPO"."CREDENTIALS" WHERE "CREDENTIAL_NAME" = '<DUPLICATE_CREDENTIAL_NAME>';

3

If a duplicate is found, delete it using the `DELETE` statement. **Caution:** Ensure you are deleting the correct credential.

DELETE FROM "_SYS_REPO"."CREDENTIALS" WHERE "CREDENTIAL_NAME" = '<DUPLICATE_CREDENTIAL_NAME>';

4

Attempt to create the new SQL credential again.

2. Verify and Update Existing Credential medium

Check if the existing credential can be updated instead of creating a new one.

1

Connect to your SAP HANA database using a tool like SAP HANA Studio or hdbsql.

2

Query the system view `_SYS_REPO.CREDENTIALS` to locate the existing credential.

SELECT * FROM "_SYS_REPO"."CREDENTIALS" WHERE "CREDENTIAL_NAME" = '<EXISTING_CREDENTIAL_NAME>';

3

Examine the details of the existing credential. If the intention was to update its properties (e.g., password, user), consider using the `ALTER CREDENTIAL` statement if available and applicable for your S/4HANA version and database configuration. If not, you may need to drop and recreate, or refer to the next solution.

4

If the existing credential's purpose is still valid and you only intended to re-establish it, you might consider dropping and recreating it after ensuring no active processes depend on it. This would involve a similar process to Solution 1.

3. Review and Correct Credential Creation Script/Configuration medium

Ensure the script or configuration used to create the credential does not have typos or unintended duplicate entries.

1

Locate the script or configuration file (e.g., .hdbsql commands, SQL script, application configuration) that is attempting to create the SQL credential.

2

Carefully review the `CREATE CREDENTIAL` statement or equivalent configuration for any typos in the credential name, or if the script is being executed multiple times unintentionally.

Example of a CREATE CREDENTIAL statement:
CREATE CREDENTIAL "<CREDENTIAL_NAME>" TYPE 'SQL' USER '<USERNAME>' PASSWORD '<PASSWORD>';

3

If the script is part of an automated deployment or provisioning process, verify that it is not being triggered more than once for the same credential.

4

Make any necessary corrections to the script or configuration and re-execute the deployment/provisioning process.
