When you release a production order you have the option to print a route card. This can be handy if you want to scan the jobs for the operations through production. The route cards lists the steps through the different operations that need to be done to produce and item. This is handy if production varies from item to item and information needs communicated to the production floor.
Here is a quick overview.
