Hi Swen, I'm a Certified SAP ABAP-BI/BW Consultant, with over 4 years of experience in developing reports, module pool, web dynpro, workflow, badis, bapis, smartforms, sapscript, etc. I really enjoy teaching, I had a experience when I was in charge of teaching a SAP ABAP IV Academy for a company in Chile, so I'll make sure to clear out all your doubts.
