This short guide “Get started with ABAP in Eclipse” gives you an introduction to the world of ABAP in Eclipse. To make the access easier we tried to show you what is different in ABAP in Eclipse compared to the ABAP Workbench. I created this guide in my first practical phase at SAP so that it must be easy to understand the information also for ABAP newbies.
