Is it possible for the IF buttons mark picked/packed to trigger my before save UE?

Yes, when “Mark Picked” or “Mark Packed” updates the Item Fulfillment, it should trigger the beforeSubmit UE.

You'd think it would. My log statement doesn't seem to be triggering in my UE though. If I use the edit form to change the status it does though.

Can you create a custom button to trigger the UE and change the status via workflow?

I could. I was hoping to avoid that since the marked picked/packed buttons are blue which is a quick eye catch for the warehouse crew.

That’s interesting — it usually should, but NetSuite often processes those buttons using XEDIT or system updates. If your script is only handling EDIT, it won’t fire. We should include XEDIT in the UE context and test again. If it still doesn’t trigger, then NetSuite might be bypassing UE for that action, and we may need an alternative approach like workflows or afterSubmit.

Don't we have pack and pick events for UE? @Christopher Quackenbush

There is a specific user event type for marking an item fulfillment as packed or shipped. It is neither xedit nor edit. Make sure your deployment is not restricted to a certain event type and that your code doeesn't return early for the wrong event types
