Avoid Duplicate Invoice

When enabled, the auto-generated numbering feature prevents assigning duplicate numbers to transactions in NetSuite. This ensures that the number cannot be edited and cannot be duplicated. Auto-generated numbering for transactions is enabled by default and cannot be disabled.

1. An administrator can go to Setup > Company > Auto-Generated Numbers.
2. Click the Transactions subtab.
3. To ensure that no duplicate transaction numbers are used, clear the box in the Allow Override column for each transaction.
4. Click Save.When you create a transaction, the number field reads To be generated. When you return to the transaction, the generated number shows in this field. For example, if you create an invoice, the Invoice # field reads To be generated. When you save the invoice, a number is assigned. If you return to the invoice at Transactions > Sales > Create Invoices > List, you can view the number for the invoice.
