SAP S/4HANA Error 466: SQL Credential Not Found
Description
This error indicates that the SAP S/4HANA system or an application within it attempted to connect to a SQL database but could not find the necessary authentication credentials. It typically occurs during operations requiring database access, such as data retrieval, reporting, or specific business processes, preventing successful execution.
Error Message
ERR_SQL_CREDENTIAL_NOT_FOUND
Known Causes
3 known causesMissing or Misconfigured Connection
The database connection details or credential references within SAP S/4HANA are either missing or incorrectly configured, preventing the system from locating the required credentials.
Invalid or Expired Database Credentials
The username or password configured for database access has become invalid, expired, or was incorrectly entered in the SAP S/4HANA system's configuration.
Incomplete System Environment Setup
Necessary environment variables, system-level configurations, or credential storage mechanisms are not properly set up on the SAP S/4HANA server or its associated components.
Solutions
3 solutions available1. Verify SAP System User and Database Connection Parameters easy
Ensures the SAP system is configured with the correct database user and connection details.
1
Log in to the SAP system using transaction code `RZ10` (Parameter Maintenance).
2
Select the relevant instance profile (e.g., DEFAULT, SID_DVEBMGS00).
3
Choose 'Display or Change'.
4
Search for parameters related to database connection. Key parameters include:
5
* `db/user`: The database user SAP uses to connect. Ensure this user exists and is active in the database.
6
* `db/password`: The password for the database user. This should be correctly set and not expired.
7
* `dbms/type`: Verify the database type (e.g., HANA, Oracle).
8
If any parameter is incorrect or missing, correct it and save the profile.
9
Restart the SAP system to apply the profile changes.
2. Check Database User Authentication and Authorization medium
Confirms the database user specified in SAP has valid credentials and necessary privileges.
1
Identify the database user configured in SAP (from RZ10, `db/user`).
2
Connect to the SAP HANA database using a database administration tool (e.g., SAP HANA Studio, hdbsql).
3
Execute a query to check the user's status and password validity. For SAP HANA, you can use:
SELECT USER_NAME, IS_ACTIVE, HAS_LOCKED_PASSWORD FROM USERS WHERE USER_NAME = '<db_user>';4
If `IS_ACTIVE` is false, activate the user. If `HAS_LOCKED_PASSWORD` is true, reset the password.
ALTER USER <db_user> ACCOUNT UNLOCK;5
If the password needs to be reset, use the appropriate database command or tool. Ensure the new password is then updated in SAP's RZ10 profile.
6
Verify that the database user has the minimum required privileges for SAP S/4HANA operation (e.g., SELECT, INSERT, UPDATE, DELETE on relevant schemas, EXECUTE on stored procedures).
GRANT SELECT, INSERT, UPDATE, DELETE ON SCHEMA <schema_name> TO <db_user>;
GRANT EXECUTE ON SCHEMA <schema_name> TO <db_user>;7
Re-test the SAP application functionality that triggered the error.
3. Refresh SAP Database Connection Cache easy
Clears and re-establishes the SAP system's internal cache of database connection information.
1
Log in to the SAP system.
2
Execute transaction code `SM59` (RFC Destinations).
3
In the 'TCP/IP Connections' or 'T/C Connections' section, locate the RFC destination pointing to the SAP HANA database (often named something like `SAP_HANA_DBSYS`).
4
Select the destination and click the 'Connection Test' button.
5
If the connection test fails with the 'SQL Credential Not Found' error, it indicates a problem with the credentials or configuration. If it passes, the issue might be transient or related to a specific application call.
6
To explicitly refresh the connection cache, you can restart the SAP application server instances. Alternatively, in some cases, a specific program or report might exist to refresh database connections (consult SAP Notes for specifics).
