Creating a Task Hierarchy

The following questions has been asked:

"[...] is there a way to set up the task hierarchy within a single project?"

and the answer is YES! To create a hierarchy within a single project, you have to set the outline level for the sub tasks. The below example creates two task, Summary Task and Sub Task. For the Summary Task, we do not set the outline level, we just create it as normal task. The Sub Task is where you set the outline level. In this example we set the outline level to 2:

Connection conn = new Connection("https://chboyd01/pwa");

WSProject.Project projWS = (WSProject.Project)conn.GetWebService(Connection.Project);

Guid sessGuid = Guid.NewGuid();
Guid jobGuid = Guid.NewGuid();
Guid taskGuid = Guid.NewGuid();

Guid projGuid = GetProjectUidFromProjectName("Excel");

projWS.CheckOutProject(projGuid, sessGuid, "");

WSProject.ProjectDataSet dsP;

 

// Create a task with a constraint

dsP =

new WSProject.ProjectDataSet();

WSProject.

ProjectDataSet.TaskRow taskRow = dsP.Task.NewTaskRow();

// Set the required fields

taskRow.PROJ_UID = projGuid;
taskRow.TASK_UID = taskGuid;
taskRow.TASK_NAME =

"Summary Task";

taskRow.AddPosition = (

int)PSLibrary.Task.AddPositionType.Last;

dsP.Task.AddTaskRow(taskRow);

projWS.QueueAddToProject(jobGuid, sessGuid, dsP,

false);

// Create a second task

dsP =

new WSProject.ProjectDataSet();

taskRow = dsP.Task.NewTaskRow();

Guid task2Guid = Guid.NewGuid();

jobGuid =

Guid.NewGuid();

// Set the required fields

taskRow.PROJ_UID = projGuid;
taskRow.TASK_UID = task2Guid;
taskRow.TASK_NAME =

"Sub Task";

// Set the start and finish dates

taskRow.TASK_START_DATE =

new DateTime(2007, 01, 31);
taskRow.TASK_FINISH_DATE = new DateTime(2007, 02, 03);

taskRow.TASK_OUTLINE_LEVEL = 2;

taskRow.AddPosition = (

int)PSLibrary.Task.AddPositionType.Last;

dsP.Task.AddTaskRow(taskRow);

projWS.QueueAddToProject(jobGuid, sessGuid, dsP,

false);

PublishProject(projGuid);

The below screen shot is the result of running the above sample code:
