EntityType: Task (ProjectData service)

Contains the properties that define the reporting data for a task in the ProjectData service.

Example

The following REST query uses the Tasks entity set and the TaskId key to get the specified task and properties. The query is all on one line.

https://<pwa_url>/_api/ProjectData/Tasks
    ?$filter=TaskId eq guid'2f333a57-f817-e211-9d84-00155d346c3f'
    &$select=TaskPercentCompleted,TaskDuration,TaskFinishDate

The following statement uses LINQ query syntax to retrieve Task entity data from the OData interface of the Project Server reporting tables. To use the statement in an application, set a service reference to the ProjectDataService, and initialize the ReportingData context. The Tasks entity set can then be accessed as context.Tasks. For more information, see Querying OData feeds for Project 2013 reporting data.

var query =
    from t in Tasks
    where (t.TaskIndex > 0)
    orderby t.ProjectName, t.TaskIndex
    select new
    {
        Project = t.ProjectName,
        Task = t.TaskName,
        TaskWork = t.TaskWork,
        TaskCost = t.TaskCost,
        TaskDuration = t.TaskDuration,
        TaskDurationVariance = t.TaskDurationVariance,
        TaskCostVariance = t.TaskCostVariance
    };

The preceding statement can be written by using Lambda expression syntax, as follows:

var query = Tasks
    .Where(t => (t.TaskIndex > (Int32)0))
    .OrderBy(t => t.ProjectName)
    .ThenBy(t => t.TaskIndex)
    .Select(t => new
    {
        Project = t.ProjectName,
        Task = t.TaskName,
        TaskWork = t.TaskWork,
        TaskCost = t.TaskCost,
        TaskDuration = t.TaskDuration,
        TaskDurationVariance = t.TaskDurationVariance,
        TaskCostVariance = t.TaskCostVariance
    });

Both preceding statements create the following REST URL (all on one line).

http://<pwa_url>/_api/ProjectData/Tasks
    ?$filter=TaskIndex gt 0
    &$orderby=ProjectName,TaskIndex
    &$select=ProjectName,TaskName,TaskWork,TaskCost,TaskDuration,TaskDurationVariance,TaskCostVariance

All three of the sample queries get the same data.

Parent element

Element

Description

ReportingData

The schema for the reporting data in the ProjectData service.

Child elements

Child elements are properties of a task and navigation properties of that task. Attributes of the Property elements specify the property name and type, and whether the property can be a null value. The NavigationProperty elements specify collections of entities, such as tasks and assignments, that are associated with a task. A navigation property uses an Association element in a query for a related entity collection

The Key elements specify the properties that are the primary keys for a task query. ProjectId is the project GUID and TaskId is the task GUID.

Property elements

The following table lists the Property elements for the Task entity. The Name, Type, and Nullable columns contain attribute values for each property.

The following table lists attribute values for the NavigationProperty elements of the Prioritization entity. The Name and Relationship columns contain attribute values for each navigation property.

Each Relationship attribute has two pairs of names; each pair of names indicates a navigation direction. The first pair starts with the entity type that has the primary, or starting, role in the navigation. The second pair starts with the entity type that has the secondary, or dependent, role in the navigation. For example, for the Assignments navigation property, the primary type is Assignment, and the secondary type is Task. For this type of navigation, the FromRole is Assignment_Task, and the ToRole is Task_Assignments.
