Currently Odoo doesn't support report for scrapped material. This module allows to get report for the scrap material. Also the scrap products can be generated from sale,purchase or while manufacturing. Here this app helps to get related source document to know from where the scrap is produced. This way user can easily manage the scraped products.
Here we generated a scrap product from the sale order 'SO114'. In inventory, 'Related Source Document' automatically gets the value of this sale order.
