I am going to read your pdf one more time. The first time around, it made me quite confused. But after a while, things are starting to make sense. But I think I need some sort of structure to hold on to. Sorry, that's the way I am. I need a theoretical cabinet in my mind so that I can put things I learn neatly. I checked a nearby Barnes and Noble bookstore. They have "SAMS Teach yourself SAP in 24 hours" book. I was leaning towards buying that but thought I'd drop a note here for you first to ask if you know a better book. Since, you seem to be a SAP guru, here in Sajha, thought I'd ask. As you can see, I am serious about learning SAP.
