Message on an Item

I have some items that I would like to have a message pop up when I enter it on a sales order.

So for example, say for item 100 when I put it on a Sales Order it tells me a message like “Ship on Dry Ice”

or for Item 200 when I enter it on a Sales Order it says “Can’t Sell in Canada”.

So when the order enter person is entering these items they are alerted immediately.

How can I do this?

You can achieve this by Restricted products configuration in Product compliance. Check the below link for more details.

Was hoping to have something pop up during Order Entry. Any way to do that?

I don’t think you will find exactly the same thing in AX, therefore you would need a customization.
