PRJ98: Scheduling Error When Linking Task to a Summary Task (181264)



The information in this article applies to:

  • Microsoft Project 98 for Windows

This article was previously published under Q181264

SYMPTOMS

In Microsoft Project 98, when you link a task to a summary task that contains an inserted project as a subtask, you may receive the following error:
This action will cause a scheduling conflict. Task <n> of "<project name>" is linked to a task that cannot move, and as a result the link cannot be honored.
Where <n> represents the number of the task and <project name> is the name of the project.

You can:

  • Cancel. Avoid the scheduling conflict.

    -or-

  • Continue. Allow the Scheduling conflict.
NOTE: If you click Continue, Microsoft Project creates the link, but does not reschedule the inserted project. However, Microsoft Project does reschedule all subtasks under the summary task that are not part of the inserted project.

CAUSE

Microsoft Project cannot reschedule an inserted project that is a subtask of a summary task, based on the summary task's predecessor relationship.

WORKAROUND

To work around this behavior, do not create a link to a summary task that contains an inserted project as a subtask. Instead, create links to the subtasks under the summary task, to create the relationship you want.

STATUS

Microsoft has confirmed this to be a problem in the versions of Microsoft Project listed above.
