According to SAP, for security purpose, it is okay to lock the user SAP* and DDIC.
I locked them in production area and after a few minutes, I had been receiving errors in Syslog like,
Logon of Jobstep User failed
So I unlocked the users again and the errors has stopped occurring.
what seems to be the problem?
We want to exercise the security options for standard users SAP* and DDIC by locking them but doing so
can affect performance in production area.
any suggestions, thanks
