The link node ID & is referenced as a higher level node

What causes this issue?

NodeID &V1& for the link node cannot be the parentID of another node
because the link node is only a reference to another node in the
hierarchy that has the same technical name. Thus the link node
<ZH>inherits</> the properties and sub-trees for this node.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Do not specify the ID for the link node as the parent ID, use the ID of
the original node instead.
