You must have serialized inventory turned on
There are several reasons why you might not be able to turn on serialization for an item.
Notes:
If you turn serialized inventory off for an item, all of the serial numbers that have been entered for that item will be removed.
Once an item with a serial number is used in a transaction, you cannot turn off serialized inventory for your company.
