Transport object &1 &2 has inconsistency

What causes this issue?

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

System Response

Because of the parallel generation in the different systems of proxy obj
ects, which are related to one ESR-object(key: ESR-name and
ESR-namespace). If these proxy objects will be transported into one
system, than the inconsistency will appear and it is not possible to
decide, which proxy object is correct for the ESR-object.
More details are in the note 886682 (part - double HashIDs).
