NEW QUESTION # 180
A company would like to send an offer letter to a candidate, have the candidate sign it electronically, and then send the letter back.What can a developer do to accomplish this?
Answer: D
NEW QUESTION # 181
A company has a custom object, order__c, that has a required, unique external ID field called crder_number_c.
Which statement should be used to perform the DML necessary to insert new records and update existing records in a list of order_c records using the external ID field?
Answer: A
Explanation:
To perform DML operations that insert new records and update existing records in a list of Order__c records using the external ID field Order_Number__c, you should use:
Option D: upsert orders Order_Number__c;
Upsert Statement:
The upsert DML operation either inserts or updates records based on whether they already exist.
By specifying the external ID field (Order_Number__c), Salesforce will match existing records based on this field.
Syntax:
upsert orders Order_Number__c;
orders is the list of Order__c records.
Order_Number__c is the external ID field used for matching.
Reference:
"The upsert statement matches the sObjects with existing records by comparing values of one field. If you don't specify a field, the upsert statement uses the sObject's ID to match data."
- Apex Developer Guide: Upsert Statements
Why Other Options Are Incorrect:
Option A: merge orders;
The merge statement is used to merge up to three records of the same object type, combining them into one. It is not suitable for upserting multiple records.
Option B: merge orders Order_Number__c;
merge does not accept an external ID field as a parameter.
Option C: upsert orders;
While this will perform an upsert based on the record IDs, it will not use the external ID field Order_Number__c for matching, which may not find existing records without IDs.
Conclusion:
Using upsert orders Order_Number__c; correctly instructs Salesforce to insert or update records based on the external ID field.
NEW QUESTION # 182
Universal Containers has implemented an order management application. Each Order can have one or more Order Line items. The Order Line object is related to the Order via a master-detail relationship. For each Order Line item, the total price is calculated by multiplying the Order Line item price with the quantity ordered.
What is the best practice to get the sum of all Order Line item totals on the Order record?
Answer: B
Explanation:
To calculate the sum of all Order Line item totals on the Order record in a master-detail relationship, the best practice is to use a Roll-up Summary Field.
Roll-up Summary Field: This field type allows you to perform calculations on a set of related records, such as summing up the total price of all Order Line items related to an Order.
"Roll-up summary fields allow you to display a value in a master record based on the values of fields in a detail record."
- Salesforce Help: Define Roll-Up Summary Fields
Master-Detail Relationship: Since Order Line items are in a master-detail relationship with Orders, roll-up summary fields can be created on the master object (Order) to summarize data from the detail object (Order Line).
"You can create roll-up summary fields on any custom object that is on the master side of a master-detail relationship."
- Salesforce Developer Guide: Roll-Up Summary Fields
Why Not Other Options:
A . Quick Action: Quick actions are used to create records, log calls, send emails, etc., and are not suitable for calculating and displaying aggregate data.
B . Apex Trigger: While triggers can perform the calculation, using them for this purpose is not considered best practice when declarative solutions like roll-up summary fields are available.
"Use declarative functionality (roll-up summary fields) for maintaining aggregates instead of triggers."
- Salesforce Developer Guide: Best Practices for Triggers
D . Formula Field: Formula fields cannot aggregate data from child records to parent records unless they are part of a roll-up summary field in a master-detail relationship.
Conclusion: Using a roll-up summary field is the most efficient and recommended approach to sum the total prices of all Order Line items on the Order record.
NEW QUESTION # 183
A software company uses the following objects and relationships:
* Case: to handle customer support issues
* Defect__c: a custom object to represent known issues with the company's software
* Case Defect__c a junction object between Case and Defect __c to represent that a defect is a cause of a customer issue Case and Defect__c have Private organization-wide defaults.
What should be done to share a specific Case_Defect__c record with a user?
Answer: A
Explanation:
Since theCaseandDefect__cobjects have aPrivateorganization-wide default (OWD), their records must be explicitly shared for a user to gain access to the relatedCase_Defect__crecord. Sharing both parent records ensures that the user can access the junction object and the associated parent objects.
