Item attribute wise different item sequential numbering

Hi!

We have a requirement to generate item numbering based on value selected in item attribute group which we are naming as item prefix and when user will select relevant value in the field, system must check the last available number against the value selected in the attribute group and accordingly populate in the item number field. Additionally, we want that different sequence, system follow based on the relevant value selected in the attribute group.
