From the "Lot No. Information List", you have the ability to change the expiry date for a Lot No. Highlighting the entry you wish to change, click 'Actions' in the ribbon and select Change Expiration Date.
Here you have the ability to enter the New Expiry Date along with a Reason Code for the change. If you do not already have "Reason Codes" set up, a new one can be created from the dropdown and used.
Pressing OK and confirming the change will update the line to reflect the new Expiry Date as well as update the Sales Expiry Date using its existing calculation from "Shelf Life requirements". Note that a New Expiry Date dated in the past can be used but a confirmation message will appear confirming the user does want to use a date from the past.
