Hi Sankar
Did the RFC user got locked ?? or the password expired.
I was just wondering If value is 0, password should not expire..
If your RFC is communication type , it will have the same password policy as that of a dialog user,
login/password_expiration_time value.
Its not a gud practice to set the value to 0 for login/password_expiration_time value.
make the RFC user system. so that password never expires.
