Salesforce Certified Platform App Builder — Question 96

At Universal Containers, the Account object has a Master-Detail relationship with an Invoice custom object. The app builder would like to change this to a lookup field, but is not able to do so.
What could be causing this?

Answer options

• A. The Account is included in the workflow on the Invoice object.
• B. The Invoice must have at least one Master-Detail field for reporting.
• C. The Invoice records have existing values in the Account.
• D. The Account record includes Invoice roll-up summary fields.

Correct answer: D

Explanation

The correct answer is D because roll-up summary fields can only be created on a Master-Detail relationship and cannot coexist with a lookup relationship. Options A, B, and C are incorrect as they do not impose restrictions on changing a Master-Detail relationship to a lookup field.
