Salesforce Exam Platform App Builder Topic 3 Question 102 Discussion

Actual exam question for Salesforce's Platform App Builder exam
Question #: 102
Topic #: 3
[All Platform App Builder Questions]

AW Computing has a custom object for service plans.

A service plan needs to be associated to one and only one contact. The support manager noticed if the wrong contact is associated, the reps are unable to change the contact. The app builder already confirmed the user has correct access to the field and there are no validations associated with the service

plans.

What could be causing the issue?

Show Suggested Answer Hide 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.

Ooh, tricky one! If the Allow reparenting checkbox is checked, the reps should be able to change the contact, so option D is probably the right answer. Unless the app builder is just playing a practical joke on the support team, in which case we're all doomed.

I think option D is the right answer. It allows child records to be reparented to other parent records.

Let's hope the app builder isn't playing a joke on us and option D is actually the solution to the issue.

Yeah, I agree. If that checkbox is checked, then the reps should have the ability to change the contact.

Haha, I bet the support manager is having a field day with this one. If the Read/Write radio button is selected, the reps should be able to edit the related records, so option C can't be the issue.

A) The Read Only radio button, Allows users with at least Read access to the Master record to create, edit, or delete related Detail records, is selected.

But what about the Read Only radio button? Could that also be causing the issue?

Hmm, the problem seems to be that the reps can't change the contact associated with the service plan. If the Allow reparenting checkbox is unchecked, that would prevent them from reassigning the contact, so option B is likely the right answer.

Yeah, I agree. If that checkbox is unchecked, it would explain why the reps can't change the contact. Option B seems like the solution.

I think you're right, option B makes sense. That checkbox would definitely restrict them from changing the contact.

I agree with Junita, if the checkbox is unchecked, it could prevent changing the contact.

I think the issue might be that the Read Only radio button is selected, which means users with only read access can't modify the related records. Option A looks like the correct answer here.

I think we should check both options A and B to see which one is causing the problem.

But what if it's actually because the Allow reparenting checkbox is unchecked? That could also prevent the reps from changing the contact.
