please explain me this

This approval process, called Approval for Package Deal, is available whenever the opportunity stage is Awaiting Approval, and it assigns approvals back to the opportunity owner. If the opportunity owner approves the discount, the opportunity record’s stage is set to Scheduled. Otherwise, set the stage to Negotiation Rejected.
