[EPM - PSI] Insert a sub task link to an existing task - TaskCannotAddWhereSpecified

28 marca 2012 14:25

Hello,

I m trying to insert, by code (calling Project.svc service), a new sub task (level 2)

The task should be postionned at a certain row, not at the end of the project document.

Here is my code:

 backendProject.ProjectDataSet prjDataSetPlanned = projectClient.ReadProject(projectId, backendProject.DataStoreEnum.PublishedStore);
                                backendProject.ProjectDataSet.TaskRow taskPredRow = prjDataSetPlanned.Task[26];
backendProject.ProjectDataSet.TaskRow taskSuccRow = prjDataSetPlanned.Task[27];

backendProject.ProjectDataSet newDataSet = new backendProject.ProjectDataSet();

Guid taskPred = taskPredRow.TASK_UID;
Guid taskSucc = taskSuccRow.TASK_UID;
Guid newTaskId = Guid.NewGuid();

backendProject.ProjectDataSet.TaskRow newTask = newDataSet.Task.NewTaskRow();
newTask.PROJ_UID = projectId;
newTask.TASK_UID = newTaskId;
newTask.TASK_OUTLINE_LEVEL = 2;
newTask.AddPosition = (int)PSLibrary.Task.AddPositionType.Middle;

newTask.TASK_NAME = taskName;
newTask.TASK_DUR = duration * 4800;
newDataSet.Task.AddTaskRow(newTask);

                backendProject.ProjectDataSet.DependencyRow dependRow = newDataSet.Dependency.NewDependencyRow();

dependRow.PROJ_UID = projectId;
dependRow.LINK_PRED_UID = taskPred;
dependRow.LINK_SUCC_UID = taskSucc;
dependRow.LINK_UID = Guid.NewGuid();

newDataSet.Dependency.AddDependencyRow(dependRow);


projectClient.CheckOutProject(projectId, newSession, "Test checkout");
bool updateActualsvalidateOnly = false;
projectClient.QueueAddToProject(JobId, newSession, newDataSet, updateActualsvalidateOnly);

projectClient.QueuePublish(JobId, projectId, false, string.Empty);
projectClient.QueueCheckInProject(JobId, projectId, false, newSession, "Update Actuals using PSI");

The insert is working but always at the end of the document.

I have 7 Tasks (Milestones) which contains multiple of sub task. I would like to insert a new sub task between the row 26 and 27.

Unfortunately, i have got an error saying that i cannot insert my task there.

First: Is it possible to insert a task where we want into an existing document ?

Second: What's wrong with my code ?

Thank you for your support.

Hi Math,

try something like this
```
task.AddAfterTaskUID = previoustask;
```
works fine for me.

Best regards

Already try,

By doing that, i have got the following error:

ProjectServerError(s) LastError=TaskCannotAddWhereSpecified Instructions: Pass this into PSClientError constructor to access all error information

Anyone had already the issue ?

Hi Fix_105,

if you set only previous task and not successor, your app work fine?

Or, if you set only
```
newTask.AddAfterTaskUID = taskPred;
```
without use DependencyRow, do you get what you want?

I hope this can helps you,

Best Regards

Hi Fix_105,

another thing; i check here: http://msdn.microsoft.com/en-us/library/websvcproject.projectdataset.taskrow.task_outline_level(v=office.12).aspx.

I don't know how your project plan is defined, but, in my opinion, you can set predecessor and successor without set TASK_OUTLINE_LEVEL.

In my opinion, you get an error because there are too many info regarding dependencies and position task.

I hope this can helps you,

Best Regards

I didn't find any solution.

For now, i just define the task as inactive (as it's for a demo) and i will activate the task once i will add.

Each time that i tried to insert the task with or without depency, the task was added at the end of the document. Could be normal. Anyway, i will do some test on a smaller project document.

Thanks for your support Paolo.
