Diagnosis
Source task &V2& is assigned to copy task &V1&. But that source taskalso, directly or indirectly, points to source task &V3& - according tothe following sequence: &V4&.
The system cannot unambiguously interpret these kinds of recursivesource task assignments and, therefore, considers them invalid.

System Response
The definition of task &V1& is inconsistent and cannot be saved in itscurrent state.

Procedure
Drop the assignment of task &V2& as the source task for copy task &V1&for now.
Check the source tasks of all tasks affected in the recursion and ifnecessary, adjust your settings.
