Identifies the entity types and the navigation properties that form the two-way association for assignments and resources.

Element

Description

Schema element: ReportingData

The schema for the reporting data in the ProjectData service.

The Assignment_Resource_Resource_Assignments association element contains two End elements that represent opposite ends of the association. The Role attribute is a lookup key that enables a navigational property to specify the direction in the association. The Multiplicity attribute refers to the entity type. Multiplicity indicates the number of entities that can be related at each end of the association: zero or one (0..1), or many (*). The Microsoft .NET implementation of OData uses 0..1 when the navigational property points to a single entity, rather than to an entity set.
