SAP Business Objects



  • SAP Business Objects encapsulate R/3 data and business processes , thus hiding the details of the structure and implementation of the underlying data.
  • To achieve this encapsulation , the SAP Business Objects are constructed as entities from several layers.
  1. First Layer , At the core of an SAP Business Object is the Kernel , which represents the object's inherent data.
  2. Second Layer , the integrity layer represents the business logic of the object.It comprises the business rules for consistent embedding in the environment and the constraints regarding the values and domains that apply to the business objects.
  3. Third Layer , the interface layer , describes the implementation and structure of the SAP Business Object , and defined the Object's interface ( BAPI ) to the outside world.
  4. Fourth layer , of business object is the access layer , which defines the technologies that can be used for external  access to the object's data . Ex : DCOM , COM( Component Object Model ).
