Thank you!!

Hi Richard, Yes I have tested your snippet on the below custom field with type date and the result is the same.

Hi, Thank you for your reply. After replacing the code with your suggestion, the same error message is displayed: Invalid date value (must be DD/MM/YYYY) For testing, when I change the field ID to the memo box, the following value is shown:

Unfortunately not. I'm already using the format.format and the other solutions I believe I'm doing the same. I can't work out why it's not working. Also, those solutions are for date time, my field is just date.

Just seen there's a specific Lot Numbered Inventory Item option on the deployment, when I changed to that it worked. Thank you!

There's one deployment assigned to inventory parts. Does that not cover all items?
