Often several routings use the same operations. Now you are able to define reference operation sets to make the definition of operations easier.
A reference operation set does not allow parallel or alternative sequences. You can assign material components, production resources and tools (PRTs), and trigger points to an operation in a reference operation set. Any assignment to a reference operation set is copied to the routing. Any change made to a reference operation set updates all the routings that use it.
A reference operation set can be created manually. Alternatively, a routing or a reference operation set can be used as a template to create it. If you copy a reference operation set from a routing, only the basic sequence is copied. If you copy a reference operation set from an existing reference operation set, there is no reference.
