Routings are used directly in production orders for a material.
A routing can be used without restrictions. Some functions from other task list types such as rate routings and inspection plans are also available in routings.
As well as a standard sequence a routing can also have parallel and alternative sequences. You can assign a routing to a material to be produced.
You can include reference operation sets in a routing as often as you like and in any order to reduce the amount of input.
