 Create a master-detail relationship between the parent and child object with a roll-up summary field that filters on the status field is the recommended method for the app builder to achieve the request of rolling up sales metrics to an opportunity for only Detailed.Sales__c records that have their picklist status set to Active. According to the Salesforce documentation, “Roll-up summary fields calculate values from related records, such as those in a master-detail relationship.” A roll-up summary field can filter on a field value of the child records and sum up only those records that match the criteria. Utilize the AppExchange to download a third-party application that can roll up the sales dollars with the appropriate filter, create a lookup relationship between the parent and child object with a roll-up summary field that filters on the status field, and utilize Apex code to roll up the desired amounts are not valid or necessary methods for this request.

The setting for the visibility of custom tabs is default off for all users when they are deployed via change sets without including the profile settings or permission sets. This means that the custom tabs are not visible in any apps or navigation menus for any users unless they are manually added by each user or by an administrator3. Option B, C, and D are not correct settings for the visibility of custom tabs.

The solution that an app builder should use to meet this requirement is master-detail relationship. A master-detail relationship is a type of relationship that creates a parent-child relationship between two objects, where the child records inherit the sharing and security settings of their parent record. The app builder can create a master-detail relationship between Supplier__c and SupplierItem__c objects, where Supplier__c is the parent object and SupplierItem__c is the child object. This way, when a Supplier__c record is deleted, all related SupplierItem__c records are also deleted automatically. Option A is incorrect because many-to-many relationship is not suitable for this requirement, as many-to-many relationship allows two objects to be linked in both directions through a junction object, but does not support cascading delete. Option B is incorrect because indirect lookup relationship is not suitable for this requirement, as indirect lookup relationship allows an external object to link with another object using an external ID field, but does not support cascading delete. Option C is incorrect because hierarchical relationship is not suitable for this requirement, as hierarchical relationship allows users to use a lookup field that links an object with itself, but does not support cascading delete.

Historical data will be updated to 12:00 timestamp when changing a Date field to Date/Time field. According to the Salesforce documentation, “When you convert a Date field to Date/Time, Salesforce appends “12:00” to existing data in your records.” The change will not be instant, but will require some time for processing. The field name will not change unless specified by the app builder. Data loss will not be experienced, but data accuracy might be affected.
