SAP introduced ABAP Objects, the object-oriented extension to the ABAP programming language, as part of SAP Basis Release 4.6. While ABAP Objects is optimized especially for business application programming, and makes ABAP development a whole lot easier, many developers still cling to the long-standing procedural approach. This article uses a simple yet practical example to compare procedural ABAP and ABAP Objects, and clearly demonstrates the benefits you can gain from using ABAP Objects. You will also learn how you can use elements of ABAP Objects to improve your existing procedural code, making it less error-prone and more maintainable, even without fully adopting ABAP Objects.
