[All CRT-403 Questions]

Northern Trail Outfitters wants to change a master-detail relationship on

Account to a lookup relationship with a custom object Park. The app builder tries to

reconfigure this but is unable to do so.

What could be causing this?

AThe Account is included in a flow process on the Park object.

BThe Park object needs at least one Master-Detail field for reporting.

CThe Account record includes Parks roll-up summary fields.

DThe park records have existing formulas on the Account.

Show Suggested Answer

Suggested Answer: C

When attempting to change a master-detail relationship to a lookup relationship, Salesforce imposes specific restrictions to maintain data integrity:

C . The Account record includes Parks roll-up summary fields. Master-detail relationships allow roll-up summary fields to aggregate data from child records onto the parent record. If any roll-up summary fields are present on the master object (Account in this case) that depend on the detail records (Parks), the relationship cannot be changed to lookup until these roll-up summary fields are removed.

To resolve this, follow these steps:

Identify and delete all roll-up summary fields on the Account object that reference the Park object.

Convert the master-detail relationship to a lookup relationship.

Recreate any necessary roll-ups using declarative tools like Process Builder or Flow if needed, as lookups do not support native roll-up summaries.

For more guidance, review Salesforce's documentation on Changing Field Types.

Wait, hold up. Is option B even a real thing? 'The Park object needs at least one Master-Detail field for reporting?' That's like saying you need a unicorn to ride a bicycle. Seriously, Salesforce?

I think we should double-check the other options to see if any of them could be causing the issue.

I agree with Virgie, it does sound like a valid reason for the issue.

I agree, it doesn't make much sense. Maybe there's another reason why the app builder can't reconfigure the relationship.

I'm not sure about that. Maybe it's just a requirement in this specific case.

Yeah, that does sound strange. I've never heard of that requirement before.

Haha, this is a classic Salesforce problem. I bet it's option A - the Account is included in a flow process on the Park object, and that's causing the issue. Good one, Salesforce!

I'm unsure. Those formulas on Account mentioned in D could mess it up too.

Option D seems the most likely to me. If there are existing formulas on the Park records that reference the Account, that would definitely make it difficult to change the relationship.

Hmm, I'm not sure. Could it be option B? The Park object needs at least one Master-Detail field for reporting, so that might be preventing the change.

Maybe, but it could also be option C, if the Account record includes Parks roll-up summary fields.

Why not? C makes sense because of roll-up summary fields.

I think it's option C. The Park records have existing roll-up summary fields on the Account, which is why the app builder can't reconfigure the relationship.
