At Universal Containers, the Account object has a Master-Detail relationship with an Invoice custom
object. The App Builder would like to change to a lookup field, but is not able to do so. What could be
causing this?
A.
The invoice must have at least one Master-Detail field for reporting.
B.
The Account record includes Invoice roll-up summary fields.
C.
The Invoice records have existing values in the Account.
D.
The Account is included in the workflow on the Invoice object.
Correct Answer: B
Explanation:
The Account record includes Invoice roll-up summary fields. This is correct because roll-up summary
fields are only available on the master object in a master-detail relationship, and changing the field
type to lookup would delete the roll-up summary fields
