TaskCannotModifyProjectSummary Error. But not updating the Project Summary Task RRS feed

  • Question

  • Hi,

    I have been trying to update few Task level custom fields for non-summary tasks using PSI. It was working for few project plans and very few plans throwing "TaskCannotModifyProjectSummary" error. In code, clearly ignoring the Project & Task summary task.

     foreach (ProjectDataSet.TaskRow tskRow in projectDs.Task)
                    if (tskRow.TASK_ID != 0 &&  tskRow.IsTASK_IS_SUMMARYNull() == false && tskRow.TASK_IS_SUMMARY == false)
                        if (statusManagerUid.Equals(Guid.Empty) == false)
                            tskRow.StatusManager = statusManagerUid;

    With curiosity, i tried to update the project without updating any custom field or any other entities. Just Read project dataset-->Checkout-->UpdateProject--> Publish-->Checkin(following is the code for the same). But still, i was getting the same "TaskCannotModifyProjectSummary". So is this something wrong with the schedule or any additional settings need to do before updating project through PSI?

                    ProjectDataSet projectDs = new ProjectDataSet();
                    projectDs = projectSvc.ReadProject(sm.ProjectUID, DataStoreEnum.WorkingStore);  
                    projectSvc.CheckOutProject(ProjectUID, sessionUid, "Updating CF Through Tool");
                    Guid jobUid = Guid.NewGuid();
                    // Update
                    projectSvc.QueueUpdateProject(jobUid, sessionUid, projectDs, false);
                    WaitForQueue(q, jobUid);
                    // Publish
                    jobUid = Guid.NewGuid();
                    projectSvc.QueuePublish(jobUid, sm.ProjectUID, true, string.Empty);
                    WaitForQueue(q, jobUid);
                    jobUid = Guid.NewGuid();
                    // Checkin
                    projectSvc.QueueCheckInProject(jobUid, sm.ProjectUID, false, sessionUid, "Updating CF. Publising through Tool");
                    WaitForQueue(q, jobUid);

    I'm happy to provide, if any further details are required to fix this problem.

    Thanks, Ram
