Learning ABAP for BPC

Hello everyone,

I understand Script logic very well, but I'd like to learn ABAP also. I've programmed in T-SQL, a bit in VB.NET, and a lot in Script logic, but I know little to nothing about how to program in ABAP.

What I'd like to start with is to find out (beginning to end) how to take something like:

*WHEN Account

*IS "Net_Income"

*REC(Factor=1,Account="Equity")

*ENDWHEN

*COMMIT

And translate that into ABAP so that I could get it to work with a BPC NW app. Is there a book I could buy that would show me end to end how to do this? Maybe a book on BW and ABAP? I don't think doing this is simple...

Thank you,

Grant
