One input and multiple output in production

Hi, I'd like to know how to handle this scenario in NAV/BC.

The routing process is to separate meat muscle and oil in purchased raw meat.

The removed oil (output) will be used as component in next routing process "cooking" with other ingredients.

in this case, input is one item-raw meat

output are two items- meat muscle and oil

example, if purchased raw meat is 1kg, output of meat muscle is 0.9kg, output of oil is 0.1kg.

can anyone tell me how to setup BOM and routing for mean muscle and oil?
