Creating a Parallel Sequence 
Use
You use this function to create a parallel sequence in a routing.
Prerequisites
The following data already exists in the system:
- General entries about the routing header data
- At least one operation in the standard sequence
Features
Only the first operation of a referenced operation set (or reference rate routing) 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 (or reference rate routing) for your parallel sequence, you must first unlock the reference.
