Salesforce Platform-App-Builder Actual Questions

The two reasons that could be preventing this relationship conversion are that there are already two master-detail relationships on the Invoice Line Item and that Invoice Line Item records exist without having the Invoice lookup field populated. A custom object can have up to two master-detail relationships, so adding another one would exceed the limit. Also, a master-detail relationship requires that the detail records have a value in the master lookup field, so any records with a blank Invoice lookup field would prevent the conversion.

The app builder should create a master-detail relationship field on the gift card object to support the requirement. A master-detail relationship field creates a parent-child relationship between two objects, where the master record controls certain behaviors of the detail record. In this case, the Account object would be the master and the gift card object would be the detail. By creating a master-detail relationship field, the app builder can meet these requirements:

Track the total number of gift cards opened and gift cards issued on an Account: This can be done by creating roll-up summary fields on the Account object that count or sum up the values from the gift card records related to each account.

Permanently ensure the gift cards are unable to be moved across any other Account once it is created: This can be done by making the master-detail relationship field required on the gift card object, which means that every gift card record must be associated with an account record and cannot be changed once set. Option B, C, and D are not types of fields that can support this requirement.

The formula that should be used to select the contact’s preferred name for email communications is IF(NOT(BLANKVALUE(Nickname__c)),Nickname__c, FirstName). This formula checks if the Nickname__c field is blank or null, and if not, it returns the value of the Nickname__c field. Otherwise, it returns the value of the FirstName field.
