Good afternoon, in my list of products in each product has a certain value example this product weighs so many kilos, already in the customer's request that product can be changed its information, I have put as filter composition producto.id = product identifier and composition product . Requestitemid = request item identifier but naontem works by changing the values in the order it also changes the composition of the product there in the product list, how could each item of an order have its specific value

If I got right, you'll have to create a new entity, that is an OrderItem entity. So when one adds a product to an order, you create an order item that points (foreign key) to a Product and an Order and has it's own attributes, composition, for example.
