If you try SAP logon and you get “account locked due to incorrect logins” error you can use one of the following methods to unlock the user:
Use RSUSR200 to list locked users,
then SU01 to unlock the user.
This is not recommended by SAP - use at your own risk
It is useful though if the locked user happens to be DDIC …
select * from SAPED1.USR02 where -- UFLAG = 64 -- account locked by administrator UFLAG = 128 -- account locked due to incorrect logins ;
update SAPED1.USR02 set UFLAG = 0 where BNAME='DDIC' and UFLAG=128 and MANDT='001'
