ABAP stands for – Advanced Business Application Programming.It is a programming language for developing applications for the SAP R/3 system.[/font][/color][color=#333333][font=Arial]
The latest version of ABAP is called ABAP Objects and supports object-oriented programming. SAP will run applications written using ABAP/4, the earlier ABAP version, as well as applications using ABAP Objects.[/font][/color][color=#333333][font=Arial]
Without further adieu , lets dive into ABAP.[/font][/color][color=#333333][font=Arial]
