Qrew LegendI think I'm more fruitful approach will be to set up notifications and daily subscription reports to the record owner warning them that they have incomplete orders.
you can also have large red morning messages on the header order record, warning them that they have not added any product
Qrew LegendIn terms of the notification, obviously it would be annoying to the user to receive a notification every time the user saved the parent record. But you could have a pipeline which would use the clock step to wait to say 10 minutes, and then check if there were children added, and then, if no children added, it could update a field, which would trigger a notification, reminding the user to add products.
