Business Application Programming Interfaces (BAPIs) are one of the most powerful tools in SAP, designed to enable seamless integration between SAP and external systems. In most cases, the standard BAPIs provided by SAP are sufficient to cover typical business scenarios.
However, real-world requirements often demand more. Maybe you need an extra field that isn’t delivered, or you have to add custom checks before the data is posted. That’s when enhancing a standard BAPI becomes necessary.
