Without enabling this stated preference, Natively NetSuite provides a VOID button on the transaction for sales order, estimate, cash sale, invoice, return authorization, cash refund, and credit memo. When using the native VOID button a reversing journal entry is not created, the transaction will be voided and any applied to transactions will have a status update of open.
When this feature is enabled, the ability to voide the previous mentioned transactions is no longer possible. However, this feature will be available for Bill Payment, Payroll Liability Payment, Customer Refund, Tax Payment and Tax Liability Check by creating a Journal Entry in the current period depending on the accounting preferences set for accounting periods.
Voiding the original set of records will need to have a new process as the Native Void button will no longer be an option.
This does not limit the transactions to "VOID" only creates an opportunity to create a new process for this action depending on if the feature is enabled or not enabled.
