I have some materials which are needed to be maintained, however their serialization cannot be done. For example a rope, or a metal shaft piece (it is installed in open and rusting etc makes it difficult to put any kind of serial data on it).
As I understand it is possible to maintain that material as an equipment (installed at a FL). The only constraint will be that this equipment will not be integrated in MM.
Am I right? Is there any other way so as to maintain it in MM too?
