• Add "last_sublot_no" (string40, nullable) to record the last-used sublot number when sublot numbers are assigned uniquely across all items in an item class.

• Add "serial_no_lvl" (int32, not nullable) to define the level of sublot or lot used to designate individual serial numbers (-1 for default for non-serialized parts).

• Add "inv_unique_by_job" (logical, default false) as a default for the same field for items created for this class.

• Add "spare1" through "spare4" (string80, nullable).
