Salesforce Updated Platform-App-Builder Exam Questions and Answers by darcie-mae

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.

 A formula field cannot be referenced by a roll-up summary field if it contains a cross-object field reference or a time-based function. A cross-object field reference is a reference to a field from a different object, such as Account. Name on a Contact object. A time-based function is a function that returns the current date or time, such as NOW() or TODAY(). Option A and C do not prevent a formula field from being referenced by a roll-up summary field.

To import opportunities with the proper country currency, the app builder needs to include the currency ISO code in all currency fields in the import file, and use Data Loader to import the records. Data Loader supports importing multiple currencies, while Import Wizard does not. The currency ISO code column in the import file specifies the currency for each record

The app builder should add the field to the custom report type field layout to troubleshoot this issue. A custom report type is a type of report that defines which objects and fields are available for reporting. The app builder can customize which fields are included in each custom report type by editing its field layout. If a new field is added to an object that is part of an unmanaged package, it will not be automatically added to the custom report type field layout. The app builder needs to manually add it to make it available as an option to add as a column in reports based on that custom report type. Option A, B, and D are not steps that can troubleshoot this issue.
