We have a company numbering scheme to mirror into Vault. The numbering scheme has been historical to our company procedures for many years and we wanted the same scheme used in the Vault. The scheme requires a number of different prefixes to help categorise the Drawings / Documents, then every Drawing / Document has a different Sequential number. However the software only allows a new seq.no if all the prefixes are the same. I would have thought our proposed scheme was a fairly standard way of setting up a numbering scheme. Please rectify for future releases.
