Business Framework Architecture (BFA) provides a structure for SAP system to connect to their partners and customers thru a specific standard.

The basic componenet of Business Framework are:

• Business components (Processes)
• Business objects (Entity/Data)
• BAPI (Business Application Programming Interfaces)
  BAPIs are interfaces for business objects. Together with the business objects, BAPIs define and document the business interface standard.
• Application Link Enabling (ALE)
  This involve distributing business objects across SAP/Non SAP system
  
  


• Communication Services
  These are the communication technologies, for example, Distributed Component Object Model (DCOM) and Remote Function Call (RFC), which the Business Framework uses to access BAPIs.
