Where are you running the job? If you are running it on the TAC, then you can find it by drilling into the Task you ran it from. If you ran it from the Studio, did you configure the AMC to be run? I suspect that maybe you have not done this. Basically if you are running from the Studio without the AMC then you will not be able to see a log unless you have set something else up yourself.
Let me check what I have in my machine. I am running my jobs in open studio and i dont think i have AMC installed. where to get it? I found on Google, but didn't find the correct URL.
I have written some tutorials on the AMC. They start here:
