Why Create Records Element?

TheCreate Recordselement adds the functionality to create a Contact record.

The Contact’s ID can then be stored on the Opportunity using a variable or field update.

Why Not Other Options?

A:Update Recordsis for updating existing records, not creating new ones.

B:Roll Back Recordsis used for rolling back transactions, not for creating records.

D:Get Recordsretrieves records but does not create them.

B: Salesforce requires that all Apex code have at least 75% test coverage in production before deployment. This ensures that the system remains reliable.

C: All triggers must have some test coverage as part of the overall 75% requirement for Apex code.

Why not other options?

A: Object visibility settings are not a deployment requirement.

D: Visual Flows do not require test coverage for deployment to production.

Apex Test Coverage Requirements

To query related child records in a lookup or master-detail relationship:

Use the parent object (Gym__c) to retrieve its child records (Trainer__c) through a nested query.

The child relationship name (Trainers__r) is derived from the lookup field.

Record-triggered flows allow automation to create tasks when an Opportunity is created. It is declarative, easy to maintain, and does not require custom code.

Steps:

Create a record-triggered flow for theOpportunityobject.

Set it to run on record creation.

Use the "Create Records" element to create a task for the Opportunity owner.

Record-Triggered Flows

Many-to-Many Relationship:

To track which companies (Accounts) report which bugs and allow multiple associations for both, ajunction objectis needed.

This junction object will have two master-detail relationships: one toBug__cand one toAccount.

Why Not Other Options?

A. Roll-up summary field: Not suitable for many-to-many relationships.

B. Master-detail field on Bug__c to Account: Creates a one-to-many relationship, not many-to-many.

C. Lookup field on Bug__c to Account: Still creates a one-to-many relationship, not many-to-many.

A. Roll-up summary fields can cause the parent record to go through Save:

When a roll-up summary field on a parent object (like Account) is updated due to changes in child records (like Branch), the parent record (Account) is implicitly saved again.

This can result in the execution of the trigger on the parent object. Developers must consider this behavior to avoid unintended recursion or infinite loops.

A: Custom objects and fields are the fundamental building blocks of the database layer in Salesforce for creating and storing custom data.

C: Roll-up summary fields are a declarative feature used to perform calculations (e.g., sum, count) on child records and display the results on the parent record.

D: Relationships (e.g., master-detail, lookup) are essential for defining how data objects are related to each other.

Why not other options?

B: Triggers are a programmatic solution, which goes against the declarative-only requirement.

E: Flows are used for automation and logic, not for building the database layer.

Salesforce Data Modeling

The@RestResourceannotation exposes an Apex class as a RESTful web service. TheurlMappingparameter defines the endpoint's URL.

The provided code attempts to update allLeadrecords in an environment with more than 2,000 records. This will likely exceed the governor limit for the total number of records processed in DML statements, which is 10,000 per transaction. To avoid this, the developer can useDatabase.updatewith batching logic.

Allow Reparenting in Master-Detail Relationships:

In a master-detail relationship, the child record (in this case, OrderItem) is tightly bound to the parent record (Order).

By default, child records cannot be reassigned to a different parent record in master-detail relationships. However, enabling the"Allow Reparenting"option on the master-detail field allows the child record (OrderItem) to be reparented to a different master record (Order).

This is the correct solution as it ensures that OrderItem records can be reassigned to a new Order without changing the structure of the relationship.

Why not the other options?

A. Add without sharing to the Apex class declaration:

Adding without sharing modifies sharing rules but does not affect the ability to reparent child records. This is unrelated to the issue described.

B. Change the master-detail relationship to an external lookup relationship:

Changing the relationship type is not necessary. Additionally, doing so could introduce unintended side effects, as master-detail relationships have features like roll-up summaries that are lost with a lookup relationship.

C. Create a junction object between OrderItem and Order:

Introducing a junction object is not required. This adds unnecessary complexity and deviates from the intended use of master-detail relationships.
