The AssignmentBaseline_Assignment_Assignment_Baseline association relates an assignment baseline to the assignments that it contains and relates an assignment to its baseline.

Definition

<Association Name="AssignmentBaseline_Assignment_Assignment_Baseline">
  <End Type="ReportingData.Assignment" Role="Assignment_Baseline" Multiplicity="0..1" />
  <End Type="ReportingData.AssignmentBaseline" Role="AssignmentBaseline_Assignment" Multiplicity="*" />
</Association>

Attributes

Attribute	Value	Description
Name	AssignmentBaseline_Assignment_Assignment_Baseline	Identifies the entity types and the navigation properties that form the two-way association for assignment baselines and assignments. In the first half of the name, AssignmentBaseline is the entity type and Assignment is the navigation property. In the second half of the name, Assignment is the entity type and Baseline is the navigation property.

Parent element

Element	Description
Schema element: ReportingData	The schema for the reporting data in the ProjectData service.

Child elements

The AssignmentBaseline_Assignment_Assignment_Baseline 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.

Role	Type	Multiplicity	Description
AssignmentBaseline_Assignment	EntityType element: AssignmentBaseline	*	There can be multiple assignment baseline entities that correspond to an assignment.
Assignment_Baseline	EntityType element: Assignment	0..1	There is one assignment for a baseline.

Remarks

One end of the association is the AssignmentBaseline entity, and the other end is the Assignment entity. The AssignmentBaseline entity type contains the Assignment navigation property, where the FromRole defines AssignmentBaseline_Assignment as the start of the association to get the collection of assignments in an assignment baseline. Similarly, the Assignment entity type contains the Baseline navigation property, where the FromRole defines Assignment_Baseline as the start of the association to get the baseline that is associated with an assignment.
