What is BDEF derived type in SAP BC-ESI-RAP - RESTful ABAP Programming Model?

SAP Term: BDEF derived type

• Component: BC-ESI-RAP

• Component Name: RESTful ABAP Programming Model

• Description: Type of an internal table or structure that is derived by the RAP framework from the CDS behavior definition. Such internal tables are used for the communication between RAP BO consumers and RAP BO providers. For that, the parameters of a method that implements RAP BO behavior are typed with BDEF derived types. In ABAP programs, BDEF derived types can be used to declare internal tables or structures to be passed to parameters of RAP handler and saver classes.

• Key Concepts: 
  BDEF derived type is a type of data structure used in the BC-ESI-RAP RESTful ABAP Programming Model. It is a special type of data structure that is derived from the BDEF (Business Data Exchange Format) standard. This type of data structure allows for the exchange of business data between different systems in a standardized format. 
  
  How to use it: 
  The BDEF derived type can be used to define the structure of the data that will be exchanged between different systems. This type of data structure can be used to define the fields, their types, and any other relevant information about the data that needs to be exchanged. Once the structure is defined, it can then be used to create a RESTful API that can be used to exchange the data between different systems. 
  
  Tips & Tricks: 
  When using the BDEF derived type, it is important to ensure that all of the fields are properly defined and that all of the necessary information is included. This will ensure that the data is properly exchanged between different systems and that no errors occur during the exchange process. 
  
  Related Information: 
  The BDEF derived type is part of the BC-ESI-RAP RESTful ABAP Programming Model, which is a set of standards and tools for creating RESTful APIs in ABAP. The BC-ESI-RAP RESTful ABAP Programming Model also includes other features such as authentication, authorization, and security.
