ABAP (Advanced Business Application Programming) is the main programming language supported on the SAP NetWeaver ABAP application server platform and the applications running on it, such as SAP ERP (formerly R / 3), S / 4HANA and CRM.
SAP uses ABAP to implement its own applications on the NetWeaver ABAP platform, and SAP customers use ABAP to modify the functionality of SAP applications or create their own applications on the NetWeaver ABAP platform. ABAP is the oldest and probably the most used of the four main SAP application platforms, which also includes SAP NetWeaver Java, SAP HANA and SAP Cloud Platform.
Evolution of ABAP :
SAP ABAP started in the 1980s as a reporting language in SAP products. He played a central role in SAP R / 3 as the main language for implementing and extending the Enterprise Planning System (ERP). Over the years, it has acquired new features, including the introduction in 1999 of object-oriented constructs, called ABAP objects, and the introduction of new methods of accessing the database and a large number of new syntax from 2010.
ABAP features are closely related to the version of SAP R / 3 or NetWeaver used. The only way to access the new language features is to upgrade to a newer version of the ABAP application server. In many cases, programs written using the features of a newer version of the application server do not run on older SAP systems.
ABAP development tools :
By far the biggest developer of ABAP code is SAP itself. However, several thousand ABAP developers work with SAP customers and consulting companies to manage and modify SAP systems. ABAP regularly ranks in the top 30 of the Tiobe Index, which tracks the popularity of programming languages.
Developers who work in ABAP typically do so in ABAP development tools (a set of plug-ins for the Eclipse open source Java development platform) or in the ABAP Workbench transaction in the SAP GUI. Both environments offer a set of development tools, ranging from code completion to automated test tools.
