SAP S/4HANA Error 420: Password Change Not Allowed
Description
This error indicates that an attempt to change a user password within SAP S/4HANA was unsuccessful because the system is configured to prevent such an action. It typically occurs due to enforced security policies, insufficient user privileges, or the current operational state of the system.
Error Message
ERR_SQL_ALTER_PASSWORD_NOT_ALLOWED
Known Causes
4 known causesSecurity Policy Restriction
System-wide security policies or client-specific configurations are in place that restrict or disallow password changes for certain user types or under specific conditions.
Insufficient User Privileges
The user account attempting to alter the password lacks the necessary authorization or role assignments to perform this sensitive administrative action.
System Maintenance or Restricted Mode
The SAP S/4HANA system may be operating in a maintenance window, a restricted mode, or during a period where specific administrative functions are temporarily disabled.
External Identity Provider
If SAP S/4HANA is configured to use an external identity provider (IdP) for authentication, password management must be handled directly within the IdP system, not S/4HANA.
