Outbound queue locked due to incorrect password

Question

Hi Gurus,
I'm having a problem to activate an Integration Model as I'm getting an error stating that the outbound queue is blocked due to incorrect password.
I have set up the RFC destination of the SCM ECC logical systems wit a valid user (I tested it). I've changed between using a Dialog user and a Communications Data user. Between every change I made I've cleaned the queue using transaction CFQ1.
Do you have an I idea of what I might be missing?
Many thanks,
Diego

Diego,
It is unclear to me which system you are experiencing the problem on.  Either way, the reasons are usually the same.  I will address establishing the ECC>SCM link.  Works the same way in the other direction.
Every time I have had the problem you are experiencing, I usually find that the fault lies with me, not the system - I have made assumptions that were not correct.
BD54 ensure that your logical system name is what you think it is.  Unless you are rigorous in your naming conventions, it is easy to become confused between logical names/hostnames/system names for SCM and ECC, ,
NDV2  ensure that the SCM system is properly identified
SM59  Make sure your IP address, or hostname is right. Make sure the system you are logging onto interactively is the one being accessed in SM59.  Make sure you have the right userid.  Password is casesensitive on some versions of R/3 and APO, but not casesensitive on others.   I always use UPPERCASE text only for PWs, at least until everything is totally debugged.
From a technical standpoint, your RFC userid can be interactive or system, I always start with interactive until the intefaces are totally debugged.  You auditors may have an opinion the final settings in the production system in this area..
