NEW QUESTION # 110
A developer created a custom order management app that uses an Apex class. The order is represented by an Order object and an OrderlItem object that has a master-detail relationship to Order. During order processing, an order may be split into multiple orders.
What should a developer do to allow their code to move some existing OrderItem records to a new Order record?

Answer: A

Explanation:
Allow Reparenting in Master-Detail Relationships:
In a master-detail relationship, the child record (in this case, OrderItem) is tightly bound to the parent record (Order).
By default, child records cannot be reassigned to a different parent record in master-detail relationships.
However, enabling the"Allow Reparenting"option on the master-detail field allows the child record (OrderItem) to be reparented to a different master record (Order).
This is the correct solution as it ensures that OrderItem records can be reassigned to a new Order without changing the structure of the relationship.
Why not the other options?
A: Add without sharing to the Apex class declaration:
Adding without sharing modifies sharing rules but does not affect the ability to reparent child records. This is unrelated to the issue described.
B: Change the master-detail relationship to an external lookup relationship:
Changing the relationship type is not necessary. Additionally, doing so could introduce unintended side effects, as master-detail relationships have features like roll-up summaries that are lost with a lookup relationship.
C: Create a junction object between OrderItem and Order:
Introducing a junction object is not required. This adds unnecessary complexity and deviates from the intended use of master-detail relationships.
