When a product/ unit is managed through a serial number, meaning that each produced unit needs to have a record of traceability associated (serial number – we scan the barcodes) if we want to keep record of a checklist for scrap we will have to confirm each quantity for this checklist even if we don´t record any scrap. In this case even if we don´t have scrap we have to confirm the checklist for each single unit produced. It should be possible to fill the checklist when there is scrap associated.
