Pass down Batch number to child items

Hi, I’m trying to set up ERPnext for a beverage company. They produce a batch of soda (with a batchnr.). After that they fill the soda into different containers. The filled containers are then sold to customers. For traceability reasons, they need to know the batchnr of the soda for each container. How can the conatainers inherit the Batchnumber from the parent? Or how should the manufacturing process be modelled, that the origin batch of the soda is always traceable. As I’m new to ERPNext and quite overwhelmed of its functionality I’d be very thankfull for your help

Best whishes,
