Autonumbering new items

[llentjes]

Is it possible to use auto-number for fields (Name/inventory number) and fill in the serial-number for each deliverd item?

When marking the items as deliverd, I would like to fill in the fields name, inventory number and serial number for each item.
Further would it be perfect to use autonumber for some fields (name and inventory-number), based on some rules.
e.g.: PC-### (and starting with 639)
