Salesforce Exam CPQ-Specialist Topic 1 Question 83 Discussion

Universal Containers has created a Discount Schedule with the override Behavior set to All Tiers and applied it to a Product. A sales rep then adds this Product to a Quote, manually changes the discount percent of a discount Tier, and saves the Quote.

At what point during the sales process can the sales rep be assured that the override amount will be unaffected by changes the Admin may make to the original Discount Schedule?
