Production order suggestion

Go to the BOM, unapprove it, add in the scrap value, approve it.

it is not working as i unapprove the version and the BOM line then edit the item by Adding the scrap percent, after that approve the BOM no effect.Does it requies any other setup.

Remove the item from the BOM, the value is written to the line when the line is inserted, it is never re-read. If you delete the line and reenter it then it will have the scrap percent.

My reference to “adding in the scrap value” related to manually adding it to the BOM.
