Why Re-Parentable Master-Detail Field?

A master-detail relationship allows Line Items to roll up totals (e.g., calculate total amount) to the Order.

Setting the relationship asre-parentablesupports moving Line Items between different Orders.

Why Not Other Options?

B. Lookup field: Does not support roll-up summary fields for calculations.

C and D: Relationships in the opposite direction (Order to Line Item) do not support the required logic.

Unit Test Scenarios:

Option Bis valid becausegetContentAsPDF()can generate PDF content for testing purposes.

Why Not Other Options?

A: Unit tests cannot execute anonymous Apex as a different user.

C: Unit tests cannot perform callouts unless mock responses are provided.

D: TheSystem.createdDatefield cannot be set manually in unit tests.

A try-catch block allows the batch to continue processing even if some records cause errors. Errors can be logged for review, ensuring the integration process does not stop entirely.

Option A: Only one method annotated with@InvocableMethodcan exist per class.

Option C: The method must bestatic.

Option E: The method can be declared asPublicorGlobalfor broader accessibility.

Invocable Methods Documentation

When an Account record is created, the following happens:

Before insert triggerincrements the count field once.

After insert record-triggered flowexecutes and increments the count again.

When the record is subsequently updated:

Before update triggerincrements the count again.

After update record-triggered flowincrements it once more.

Thus, the final value of thecountfield =4.

Order of Execution in Salesforce

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.

Roll-Up Summary Field:

Since the relationship between Order and Order Line Item is aMaster-Detail, a Roll-Up Summary field can be used on the Order object.

The MAX function in a Roll-Up Summary field calculates the latest date (the maximum value) among all the availability dates on the Order Line Items.

Why MAX Roll-Up Summary Field Works:

The latest availability date among the Order Line Items will determine when the entire Order can be shipped.

Why Not Other Options?

AandB: There is no such formula called "LATEST" or "CEILING" applicable to date fields.

C: A COUNT Roll-Up Summary is irrelevant for calculating dates.

Execution Flow:

The loop runs 500 times (iranges from 0 to 499).

In each iteration, a newAccountrecord is created and inserted.

Governor Limits:

This code violates the governor limit of 150 DML statements per transaction because eachinsertis executed individually.

However, the code logically attempts to insert 500 accounts.

Key Consideration:

The code demonstrates inefficient handling of DML operations and would fail in a real-world scenario.

Polymorphic Lookup Fields:

These fields can reference multiple object types.

Example: TheWhatIdfield on Event can reference any object that is related to the Event, such as Account or Opportunity.

Why Not Other Options?

A:ParentIdon Account is not polymorphic; it only points to other Accounts.

B: Custom fields cannot be polymorphic.

D:LeadIdandContactIdare specific fields, not polymorphic.

Upload the SVG file as astatic resourcein Salesforce.

Import it in the LWC JavaScript file and define it as a property.

Reference the property in the component’s HTML template.

Example:

importmySvgfrom'@salesforce/resourceUrl/mySvg';

exportdefaultclassMyComponentextendsLightningElement{

svgUrl = mySvg;

}
