Temporary assignment to own parent position

Summary

We frequently have a need to temporarily assign a worker to his own parent position. When we update his original assignment with action Add Temporary Assignment, if we assign hem to his own parent position, when submitting the change, we get the error message:

The person ID of the manager is the same as the person ID of the managed worker or nonworker. (PER-1530260).

despite the fact that the original assignment status is being changed to suspended.

Are we doing anything wrong?
