ABAP for newbies
To download the examples source code to your system you must install abapGit: https://github.com/larshp/abapGit
For coding i'm using the free SAP Netweaver 7.51 SP02 Developer Edition (https://blogs.sap.com/2017/09/04/newbies-guide-installing-abap-as-751-sp02-on-linux/)
