You use this function to create an alternative sequence in a routing.

The following data already exists in the system:

• General entries about the routing header data
• At least one operation in the standard sequence

You can enter a lot-size range, so that the system automatically selects the alternative sequence if an order lies within this range. The lot size range of an alternative sequence can differ from the one specified in the routing header. However, it must overlap at least partially with the lot size range in the routing header.

Only the first operation of a referenced operation set that has not been unlocked can be used as a branch or as a return operation for alternative or parallel sequences. To use other operations within a reference operation set for your alternative sequence, you must first unlock the reference.
