# Failed to export into Oracle NetSuite. Document number for this expense is already used for this vendor.

## Error message

```plaintext
Failed to export into Oracle NetSuite. Document number for this expense is already used for this vendor.
```

## Affected ERP integrations

- Oracle NetSuite

## Cause

This error occurs when the document number assigned to an expense in Payhawk has already been used for another transaction with the same vendor in Oracle NetSuite. Oracle NetSuite typically enforces uniqueness for document numbers per vendor to prevent duplicate entries and maintain accurate records.

## Solution

To resolve this issue:

1. In the [Payhawk Web Portal](https://portal.payhawk.com), go to **Spend** and open the expense that failed to export by clicking on it.
2. Locate the document **Number** field.
3. Change the document number to a unique value that has not been previously used for this vendor in Oracle NetSuite.
4. Save the updated expense.
5. Attempt to export the expense again.
