How To Fix UAMO019 - Source and target of copy must be different

SAP Error Message - Details

• Message type: E = Error

• Message class: UAMO - UA Modeler

• Message number: 019

• Message text: Source and target of copy must be different

What causes this issue?

You attempted to copy a cost estimate in the working environment.
As the system always attempts to insert the new generated copy as a
subobject under the element when copying a cost estimate, the
destination of the copy is implicitly determined by the operation steps
you 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 system
cannot process.

System Response

You cannot create the copy in the current position.

How to fix this error?

Choose the menu function <ZH>Copy</> from the context menu of an element
that is different from the element that you want to copy.
