- CDS Behavior Definition Header, Abstract BDEF

implementation type;
$[strict;$]
$[with hierarchy;$]
entity behavior definition ...

Effect

The CDS behavior definition header of an abstract BDEF can define the attributes listed below. The implementation type is mandatory, strict and with hierarchy are strongly recommended for the following reasons: strict mode ensures that no outdated syntax can be used. When leaving out with hierarchy, the abstract BDEF represents the same derived type as a single CDS abstract entity and doesn't offer any additional value.

• implementation type: an abstract BDEF must start with the keyword abstract.

• strict: It is strongly recommended that BDEF strict mode is used.

• with hierarchy: causes the construction of a new kind of BDEF derived type for the entities that are part of the BDEF: Beginning at the root entity, such a type contains all entity fields, plus a component for every composition. For a composition with cardinality <= 1, this component is a structure; otherwise, the component is a table. The type of the component (or its line type) is defined recursively in the same way, down to leaf level in the CDS composition hierarchy.

The behavior definition header is followed by an entity behavior definition.

Note

The addition with hierarchy is a precondition for the following components of an abstract BDEF:

• with control

• deep mapping

• scalar entity

• association _Assoc with hierarchy
