Diagnosis
You attempted to copy a cost estimate in the working environment.
As the system always attempts to insert the new generated copy as asubobject under the element when copying a cost estimate, thedestination of the copy is implicitly determined by the operation stepsyou have executed.
You have entered the cost estimate to be copied (source) as the target.However, this would result in a circular structure that the systemcannot process.

System Response
You cannot create the copy in the current position.

Procedure
