How to restrict users to update LOT Expiration date on work order transaction

Hi Everybody,

We are having a situation wherein the LOT Expiration date is editable during the work order transaction.

When we create a work order then we would be creating below transactions

i. Report Material Transactions

ii. Review dispatch list

When we create review dispatch list for a work order for a LOT controlled item then we observe that LOT expiration date is editable for existing LOT's. It should be editable for new Lots. But it shouldn't be editable for existing lots since the expiration date should be same for all items in that LOT.

It's misleading the business. Could you please let us know if we can have any personalisation on LOT Expiration date field for existing LOTs.
