What is causing the MSP Error message that duration of fixed-duration task will change?

Why is the following error message generated when  opening a project from Clarity PPM to Microsoft Project (MSP)? This seems to always generate on the last task of the project, but if we delete that task, it errors on a different task ID.

The resource is assigned outside the original dates for task <ID> <Task Name>. The duration of this fixed-duration task will change to accommodate the resource assignment.


Component: ODMSP


This is by design if the resource is over allocated for the duration of the task, as even fixed duration tasks duration will increase when exported to MSP to accommodate for the over allocation. But unlike other task types that will just adjust the task duration without warning, you will be warned by MSP with Fixed Duration tasks that the duration is increasing. The error is only generated for one task (the last task in the WBS with the issue), so if the issue is corrected for that task (or the task is deleted), it will error on the next task that has the issue from the bottom order of the WBS. 

If you are on 14.4 or 15.1 of the MSP New Driver, see the following KB for a defect you can run into: KB000007143
