|Business Application Programming Interface (BC-MID)|
A standardized programming interface that facilitates external access to business processes and data in the SAP System.
You define Business Application Programming Interfaces (BAPIs) in the Business Object Repository (BOR) as methods of SAP business objects or SAP interface types.
BAPIs offer an object-oriented view of business components in the SAP system. They are implemented and stored as RFC-enabled function modules in the Function Builder of the ABAP Workbench.
