Structure Tab Page 

Use

You use the Structure tab page to view the structure of a business object. You may also change the following properties of an attribute:

·        Custom Key – when this property is on, the attribute is a part of the custom key of the business object node. This property is not available for the default attributes (createdBy, createdAt, modifiedAt, modifiedBy), subattributes of complex attributes, and attributes, which are of unlimited length (CLOB, BLOB).

·        Optional CREATE Attribute – this property is available only for optional attributes (with cardinality 0..1). When this property is on, the attribute is a part of the create operation (by default, only the mandatory attributes can be set using the create operation).

You use these data types to generate tables, define table relations, and implement basic methods for reading, writing, updating, deleting, and querying data.

Structure

The Structure tab page can be divided into the following views:

·        Existing Types

·        Structure Fields

·        Properties

Existing Types

The Existing Types view lists structures and simple types available in CAF  and also the ones you have created in your application.
