ABAP RESTful Application Programming Model - Behavior Implementation Class

This post explains the class where the behavior definition methods are implemented. This is covered in various posts of the ABAP RAP Series, however the methods are scattered across the posts. A business object is implemented through a specialized class pool that references its behavior definition. When the unmanaged implementation type is used, developers must implement all the behavior. This…

ABAP RESTful Application Programming [24] – External Numbering and Managed Early Numbering

This post talks about Numbering in RAP BO. Numbering means setting up values for the primary key fields of the entity. The primary key can consist of one or more fields. Options to handle Numbering Options are determined by when the numbering is handled and who handles it. Early and Late Numbering (When it is handled?) Early Numbering As the name suggests, the numbering is handled early i.e.…

ABAP RESTful Application Programming [22] – Determinations and Side Effects

This post talks about adding determinations to a RAP BO along with side effects. Determinations A determination modifies instances of business objects based on trigger conditions. Trigger conditions can be modify operations such as create, update, and delete and modified fields. The determination can calculate field values, modify entity instances and return messages to the consumer by passing…
