When NetSuite's Allow Override preference is enabled for auto-generated numbers, ZoneReconcile may generate duplicate invoice numbers or assign no number at all during mass transaction creation. This article explains how to disable the setting and clean up any affected records.
Overview
A known issue occurs in ZoneReconcile when the native NetSuite Allow Override preference for auto-generated numbers is enabled. This setting allows the system to bypass standard sequencing logic during mass transaction creation, which can result in 2 symptoms:
- Duplicate invoice numbers — multiple transactions share the same document number.
- Missing invoice numbers — no number is assigned, and the transaction name defaults to a generic "transaction type + date" format.
Important: Resolve the Allow Override setting before running any additional mass transaction batches to prevent further duplicates.
Resolution
Disable the Allow Override preference in NetSuite to restore correct sequencing behavior.
- Navigate to Setup > Company > Auto-Generated Numbers.
- Locate the relevant transaction types (for example, Invoices, Credit Memos, or Sales Orders).
- Clear the Allow Override checkbox for each applicable transaction type.
- Save the record.
Cleanup steps
After disabling the override, follow these steps to identify and correct any transactions affected by the duplicate numbering issue.
- Identify duplicates: Run a saved search to find transactions with duplicate document numbers or transactions named using the "type + date" format.
- Remove incorrect payments or journals: Select the Delete Payment Transactions button (if your role permissions allow) to remove incorrectly created records.
- Clean up test data: Update and remove any test records before moving to a production deployment to ensure the numbering sequence is reset and accurate.
- Verify sequencing: Run a small test batch after disabling the override to confirm the transaction creation script is sequencing document numbers correctly.
