Splitting Jobs 

Sometimes, you may want some of the records in a job to proceed even though you have not finished processing all of them. To achieve this, you can split some of the records into a new job and send one of them on its way while you continue processing the records of the new job.

Whether any assignee or just the owner or the launcher can split a job is based upon the setting of the Split Job property of the Start step or the Approve step.
