In OData (Open Data Protocol), an entity is a representation of a data record that typically maps to a row in a database table.

Key Concepts:

• Entity = Object or Record

  • For example, a Customer, Order, or Product can each be entities.

• Entity Type

  • Defines the structure of an entity: its properties (fields) and key (unique identifier).

Steps

1. Expand the Data Model
2. Right-click Entity Types → Select Create.

   

3. Enter:
   1. Entity Name: SalesOrder
   2. ABAP Structure: VBAK (optional but helpful)
   3. Mark Key Field (e.g., VBELN)

Press Enter and confirm field generation.

Repeat this to create another Entity Type SalesItem (based on structure VBAP).
