Lightning Component Benefits

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.

B: Using partial DML statements (e.g.,Database.insert(list, false)) allows only valid records to be committed while identifying invalid ones, avoiding runtime errors.

D: TheDatabase.Savepointmethod ensures transactional control by allowing rollback to a specific savepoint if an error occurs.

Why not other options?

A: The@ReadOnlyannotation is for read-only operations and would not allow DML operations.

C: TheSystem.Limitclass helps monitor limits but does not directly control transaction behavior.
