What he said. After the patrol is finished, go back into SH3 Commander and click on your career. At the bottom, under 'Click For Available Actions', click 'Update Your Personnel File'. Commander will then create the file for your captain. There you can click on 'Patrol 1' and you'll see all the results. Once that is done you can go back into SH3 itself and when you look at the patrol report it will be updated with the Ship Names, Cargo Types and Crew/Losses. This is the only way Commander can do it. It's also the best way, because what you see is information that you wouldn't know until after it had been confirmed by BdU, and sometimes not even until after the war was over.
Oh, and also what he said: WELCOME ABOARD!
