SAP ABAP is a high-level language that is primarily used to develop enterprise applications for a large business and financial institution on the SAP platform. Currently positioned along with Java, as the main language for SAP application server programming, most of the programs are executed under the control of the run-time system.

This technique is done through SAP BDC (Batch Data Communication). BDC sessions, which are also known as Batch Input Sessions, are used to load legacy data into the SAP system and perform highly repetitive tasks that involve in data entry.
