Explanation: * Scenario: The Create MonthlyTotalsReport() method must lock the data and prevent others from updating or inserting new rows until complete. * Serializable: A range lock is placed on the DataSet, preventing other users from updating or inserting rows into the dataset until the transaction is complete.
