Reviewing API and Business Function Documentation
You can use JD Edwards EnterpriseOne business functions and APIs in custom integrations. Business functions groupings are:
Master Business Functions
A collection of business functions that provide the logic and database calls that are necessary to extend, edit, and commit the full transaction to the database. The design of master business functions enables them to be called asynchronously and to send coded error messages back to calling applications.
Major Business Functions
Components that encapsulate reusable logic common to many applications, such as date editing routines and common multicurrency functions.
Minor Business Functions
Components that perform complex logic for a specific instance or single application. Minor business functions are used in JD Edwards EnterpriseOne for processing that cannot be accomplished efficiently in event rules or for logic that might be required in multiple places within a single application.
