ナビゲーションプロパティ
In OData, a navigation property is a property on an entity that is itself either a single entity or list of entities.
A single-entity navigation property signifies a one-to-one relationship; for example, SAP Cloud for Customer has only one Account per AccountTeam. In SAP Cloud for Customer, Account is a navigation property on Account Team.
An entity set navigation property signifies a one-to-many relationship; for example, in SAP Cloud for Customer many AccountTeams can belong in the same Account. In SAP Cloud for Customer, AccountTeam is a navigation property on Accounts, which contain multiple AccountTeams.
Working with Navigation Properties Relationally
Navigation properties in OData link related entities. Similarly, in a relational database, a foreign key serves to link tables. While OData can support foreign key references between related entities, SAP Cloud for Customer does not use them. Instead, relationships between entities can only be determined using the navigation properties.
Select
Navigation properties will be displayed as views. They can be selected directly from just like any normal table. See ビュー for more information on querying navigation properties.
Insert
The connector supports deep inserts. See テーブル for more information on specifying navigation properties when you create an entity.
