Master-detail relationships allow roll-up summary fields to aggregate data from child records. If a roll-up summary field exists on the Account object, the relationship cannot be changed to a lookup because lookup relationships do not support roll-up fields.

Why not other options?

A: Null values in the Vendor records do not prevent the change.

C: Custom fields can have their types changed as long as dependencies like roll-up fields are not present.

D: Organization-wide defaults do not affect the ability to change relationships.

The Apex Interactive Debugger allows developers to step through code execution in real time, which is the most effective way to identify the root cause of the duplication issue.

To preserve the value of maxAttempts for the length of the Apex transaction and share its state between trigger executions:

Static Variable:

Static variables are initialized once per transaction and retain their value throughout the transaction.

They can be accessed without instantiating the class.

Private Scope:

Declaring it as private ensures encapsulation and prevents unintended external modification.

Helper Class:

Using a helper class ensures the separation of concerns, keeping trigger logic clean and adhering to best practices.

Example Code:public class HelperClass {

private static Integer maxAttempts = 5; // Default value

public static Integer getMaxAttempts() {

return maxAttempts;

}

public static void setMaxAttempts(Integer attempts) {

maxAttempts = attempts;

}

}

A: Constants (static + final) cannot be modified after initialization.

B: Trigger member variables cannot retain values across executions within the same transaction.

C: Declaring it as a non-static variable in a helper class would reset its value during each trigger execution.

Why Not the Other Options?

Why WITH SECURITY_ENFORCED?

Ensures field-level security and sharing rules are enforced in SOQL queries.

Prevents unauthorized records or fields from being accessed or displayed.

Why Not Other Options?

B and C: with sharing and inherited sharing enforce record-level access but do not handle field-level security.

D: without sharing ignores sharing rules, which would display all records regardless of user permissions.

ï‚· Option B: Custom events in LWC allow data to be passed using the detail property of the CustomEvent object. This is the recommended way to pass data in a custom event.

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 as re-parentable supports 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.

References:

Based on the provided code, an exception is likely being thrown if a required field is missing or if there are validation rules that the record does not meet. Salesforce will throw an exception when an attempt to create a record violates constraints.

Why not other options?

B: Salesforce reports errors for failed DML operations unless they are handled in a try-catch block.

C: The record cannot be created successfully if constraints are violated.

D: Debug logs may provide details, but the record creation would fail.
