Hi Juergen Pitz,
okay I see your point. I thought that the serial numbers could be randomly transferred to the HU's, because as a user I don't care to which HU the serialized material was connected to. I never have the case that I have to assign a certain HU to a certain material. But okay - I understand your point. I'll still try a subpackage instruction - but I think I'll have to do it manually anyways :)
Thank you very much for your response.
Sincerely,
Dennis
