Parameter documentation

If a logon attempt fails, in some cases detailed error messages are displayed that could provide a possible attacker with information about the existence of a user. On the other hand, error messages of this type are very helpful for legitimate useres and can help to reduce queries to the system administrator. You can use this profile parameter to choose the desired behavior. The Security Audit Log and the trace information contain the detailed error codes in any case (see also: SAP Note 320991), to allow the system operator to analyze logon problems.
See SAP Parameter Documentation for full SAP documentation for this profile parameter.
