Bw-specific abap book or materials

Question

dears,
could you provide me info on how I can access  to the above materials?
we know that BW abap is specific in the sense that its done primary in background for manipulation of data, so not entirely like R/3 Abap.
I need to get up to speed on BW abap.
I know common routines like datapackage manipulation. But not so sure how function modules are used in BW.
Ideally, I would like to get hold of such a book where it shows full codes for real example scenarios and the various ways to code to manipulate data.
I think such a book has definite market value.
regards
suzie
