Shipment email workflow I have a workflow to send an email when the status of the IFUL = Shipped. Triggers after record submit. I do not want it to trigger again if the IFUL is edited for any reason (maybe a Memo is edited for example). I've tried to set it so the (old.status <> Shipped) and (status = Shipped) but that doesn't trigger. We sometimes so straight to Shipped (bypassing Picked/Packed) so cannot use those as a filter. I've also tried the NOT (old.status = Shipped)... but that doesn't work either. Anyone have a solution?

Not sure if it's possible in a Workflow, in a User Event script there's a specific triggering event of "SHIP" much like "APPROVE" on a Sales Order, maybe you could look at that as a resolution? (Not suggesting you switch necessarily to a UE script just that the same trigger may be available) In help see: https://<yourAccountID>.app.netsuite.com/app/help/helpcenter.nl?fid=section_4407992070.html

In most of our workflow emails, we have a checkbox called Email Sent that is checked by the workflow when the first email is sent. It is also used as a criterion to prevent resending of the transaction. It may also be applicable to you.
