I'm a brazillian developer. I used to work with web development nowadays, but in the recent past I worked with AdvPl (TOTVS - Protheus) and a lot of business development. I got 5 years of experience, and I built my own ERP for a small company. So, I saw a lot of information about ABAP, Sap Hana and I feel lost with such information. I'm really interested about the SAP systems, so I want some light to know where do I start in this new world. Thank's in advance.
