SAP S/4HANA Error 416: User Account Locked
Description
This error indicates that the user account attempting to log into SAP S/4HANA or access a specific database resource is currently locked. It prevents any further system access for that user until the lock is released.
Error Message
ERR_SQL_USER_LOCKED
Known Causes
3 known causesExceeded Login Attempts
The user account was automatically locked by the system security policy after too many consecutive incorrect password entries.
Manual Account Lock
An SAP S/4HANA administrator has manually locked the user account, often for security reasons or during an investigation.
System Security Policy
The account may be locked due to a system-wide security policy, such as after a password reset or during specific system events.
Solutions
3 solutions available1. Unlock User Directly in SAP GUI easy
Quickly unlock a user account via SAP GUI transaction SU01.
1
Log in to your SAP S/4HANA system using SAP GUI with a user that has authorization to manage user accounts (e.g., a super administrator or a role with transaction SU01 access).
2
Execute transaction code SU01.
3
In the 'User' field, enter the username of the locked account and press Enter.
4
On the user maintenance screen, navigate to the 'Logon Data' tab.
5
Under the 'Logon Attempts' section, you will see a checkbox labeled 'Lock'. If this checkbox is ticked, uncheck it.
6
Click the 'Save' button (or press Ctrl+S) to apply the changes.
7
Inform the user that their account has been unlocked and advise them to try logging in again. It's also good practice to suggest they reset their password if the lockout was due to repeated incorrect entries.
2. Unlock User via SAP HANA SQL (for direct database access scenarios) medium
Unlock a user account directly in the SAP HANA database if the error is occurring at the database layer for specific applications or direct access.
1
Connect to your SAP HANA database using a SQL client (e.g., SAP HANA Studio, DB Visualizer, or command-line tools like hdbsql) with administrative privileges.
2
Execute the following SQL statement to unlock the user. Replace 'YOUR_USERNAME' with the actual username of the locked account.
ALTER USER YOUR_USERNAME ACCOUNT UNLOCK;3
Verify the user's status. You can do this by querying the 'USERS' system view. For example:
SELECT USER_NAME, IS_LOCKED FROM "SYS"."USERS" WHERE USER_NAME = 'YOUR_USERNAME';4
If the 'IS_LOCKED' column shows 'FALSE' (or 0), the user has been successfully unlocked. If the error persists, investigate further, as it might be a session-level issue or a different underlying cause.
3. Investigate and Reset Failed Login Attempts medium
Analyze failed login attempts and reset them to prevent future lockouts.
1
Log in to SAP S/4HANA using SAP GUI with administrative privileges.
2
Execute transaction code SU01.
3
Enter the locked username and press Enter.
4
Navigate to the 'Logon Data' tab.
5
Observe the 'Logon Attempts' counter. If it's high, this indicates repeated failed login attempts.
6
To reset the failed login attempt counter without unlocking the user (if you want to force a password reset), you can use transaction code ST05 to trace the user's activities and identify the source of repeated incorrect passwords, or you can manually reset the counter via SE16/SE16N on table USR02 (use with extreme caution and only if you understand the implications). The more common approach is to simply unlock the user via SU01 (as in Solution 1) and advise them to reset their password.
7
If the lockout is recurring, instruct the user to reset their password. This can be done via transaction code 'SU01' (for administrators) or by the user themselves if they have the 'Password Change' authorization and can access a system where they can initiate a password reset.
