Question 441 · 469 in bank
Universal Containers has a junction object called Billings with a primary Master-Detail relationship with Accounts and a secondary Master-Detail relationship with Orders. The app builder has a requirement to change the primary Master-Detail relationship to a Lookup. What happens to the secondary Master-Detail relationship with Orders?
Show answer
Answer: C
Explanation
C: If you delete the primary master-detail relationship or convert it to a lookup relationship, the secondary master object becomes primary. Roll-up summary fields that summarize data from the junction object can be created on both master objects. If you delete the primary master-detail relationship or convert it to a lookup relationship, the secondary master object becomes primary.
