 Alternative Sequence Locate this document in the navigation structure


A linear sequence of operations that is an alternative to a sequence of operations in the standard sequence.


You use an alternative sequence for example, if

  • The production flow is different for certain lot-size ranges

For instance you can machine a work piece on conventional machine or on NC machines. A NC machine has a longer set-up time than a conventional machine. However the machining costs are considerably less. Therefore whether you use NC machines will depend on the lot size.

  • The production flow changes under certain business conditions.

For instance, if you have a capacity problem, you have some production steps performed externally by a vendor.


You can only create alternative sequences in routings. You cannot create them in reference operation sets, reference rate routings or rate routings.
