SAP S/4HANA Error 332: Invalid SQL User Name
Description
Error 332, ERR_SQL_INV_USER, indicates that the system attempted a database operation with a username that is not recognized or does not exist in the underlying SAP HANA database. This typically occurs during login attempts, data access, or when an automated process tries to connect with invalid credentials.
Error Message
ERR_SQL_INV_USER
Known Causes
4 known causesIncorrect Username Entry
The username was typed incorrectly, containing typos, extra spaces, or a mix of cases that does not match the registered user.
User Account Does Not Exist
The specified user account has either been deleted, never created, or is not active within the SAP HANA database or connected user management system.
Wrong System/Client Context
The user is attempting to log into or access a database in a different SAP S/4HANA system or client where their specified username is not valid.
Case Sensitivity Mismatch
Some database systems are case-sensitive for usernames. If the entered username's casing does not exactly match the stored username, it will be considered invalid.
Solutions
3 solutions available1. Verify SAP System User and Database User Mapping easy
Ensure the SAP system user is correctly mapped to a valid database user.
1
Log in to your SAP S/4HANA system using a client with administrative privileges (e.g., SAP GUI with SAP_ALL/SAP_NEW authorizations).
2
Execute the transaction code SU01 (User Maintenance).
3
Enter the SAP system user ID that is causing the error and press 'Display'.
4
Navigate to the 'Logon Data' tab.
5
Under the 'User Type' section, identify the 'User Group' or 'User Type' that dictates database access. For database connections, this is often an 'System' or 'Dialog' user with specific authorizations.
6
Crucially, check the 'System User' field (if applicable) or any parameters that link this SAP user to a database user. For example, some older configurations might have a direct mapping. In modern S/4HANA, this is often handled through the user's profile and roles that grant database access.
7
If a direct database user name is specified or implied, verify its existence and validity within the underlying SAP HANA database. You can do this by connecting to the HANA database using SAP HANA Studio or `hdbsql` and checking for the existence of that user.
SELECT * FROM SYS.USERS WHERE USERNAME = 'DATABASE_USER_NAME';8
If the database user does not exist or is invalid, create it in SAP HANA or correct the mapping in SU01. If the SAP user is intended to use the system's default database user (e.g., for background jobs or RFCs), ensure that default user is correctly configured and authorized.
2. Validate SAP HANA Database User Credentials medium
Confirm that the database user specified by the SAP system is valid and has the correct privileges in HANA.
1
Identify the database user that the SAP S/4HANA system is attempting to use for the connection causing the error. This information might be available in SAP system logs (SM21), trace files, or the configuration of the specific application or interface that is failing.
2
Connect to your SAP HANA database using a tool like SAP HANA Studio or the `hdbsql` command-line client.
hdbsql -u SYSTEM -p <system_password> -n <host>:<port>3
Execute a SQL query to check if the identified database user exists and is active.
SELECT USER_NAME, IS_ACTIVE FROM SYS.USERS WHERE USER_NAME = 'TARGET_DB_USER';4
If the user does not exist or is not active, create or reactivate the user in SAP HANA. Ensure the user is assigned to the correct roles and privileges required for the SAP S/4HANA operations.
CREATE USER TARGET_DB_USER PASSWORD '<password>';
GRANT <role_name> TO TARGET_DB_USER;5
If the user exists and is active, verify its password. If the password has expired or is incorrect, reset it.
ALTER USER TARGET_DB_USER PASSWORD '<new_password>';6
Ensure the database user has the necessary authorizations to perform the operations requested by the SAP S/4HANA system. This often involves granting privileges on specific schemas, tables, or procedures.
GRANT <privilege_type> ON <object_name> TO TARGET_DB_USER;3. Review SAP System Profile Parameters for Database Connectivity medium
Check SAP system profile parameters that influence database user handling.
1
Log in to your SAP S/4HANA system using SAP GUI with administrative privileges.
2
Execute the transaction code RZ10 (Profile Maintenance).
3
Select the relevant instance profile or default profile for your SAP system.
4
Choose 'Display' or 'Change' and search for parameters related to database user names or credentials. Common parameters that might indirectly affect this include those related to RFC destinations, background job users, or specific application configurations.
5
Pay close attention to parameters that might specify a default database user for system processes or background tasks. For example, `rsdb/sys_usr` or similar parameters might be relevant in some contexts, though S/4HANA's HANA integration is more robust.
6
If any parameters appear to be incorrect, outdated, or missing, update them accordingly. After changing any profile parameters, you will typically need to restart the SAP instance for the changes to take effect.
7
Consult SAP Notes or documentation specific to your S/4HANA version and the failing component to identify any critical profile parameters for database connectivity.
