Request & invalid; enter all objects in request &

What causes this issue?

An SAP Note correction that you previously implemented with the Note
Assistant was delivered with a Support Package or an upgrade. The
corrected objects now have to be reset to their original state. To do
this, the correction instructions and all the corrected objects have to
be entered in the same change request. The correction instructions are
already locked in request &V2&, and one of the objects is locked in
request &V1&.

System Response

The system cannot reset the objects in the correction instructions.

How to fix this error?

Make sure that the correction instructions and all the objects that
they contain can be locked in one request (by merging &V1& and &V2&,
for example). Restart the function afterwards.
