Seeing that you have asked three questions in a row, I will simply say that the production mode of industrial enterprises and catering enterprises is different. The products of industrial enterprises are composed of a variety of materials, which can be queried according to the BOM list. How much each material is used, the loss rate is very clear, and this research and development stage has been determined.

After the cost accounting of industrial enterprises, the cost of each product is very clear. If it can't be sold, it will form the company's inventory, while the catering enterprises have a fast flow of water and very little inventory.
