Expiry date with Serial No but no Batch No?

Hi,

I am trying to track expiry dates of items. The Item has a serial number but no batch number. I’m noticing the “Has Expiry Date” option of the Item doctype only appears when “Has Batch No” is checked.

Is it possible to track expiry when items are only assigned a serial number and not a batch number?

Thanks and kind regards,
DW
