Re: I need to learn SAP shipping module
Contact SAP Switzerland and you can go on a training course. Some are even in English. I find the courses to be far more useful than the SAP Press overview books, which are often woolly and very general.
However, learning the shipping module and having experience of it are two quite different things. If you've done the training, then that's definitely in your favour, so I recommend doing it, but a candidate with experience will win most times.
