Fortnox error: 2001897

Description

The action on the invoice failed because the voucher to be created in Fortnox contains fewer than two voucher lines. Fortnox requires at least two lines (double-entry bookkeeping: debit and credit). The message about missing “credit-invoice events” is informational; the main error concerns the voucher.

Cause

• Only one voucher line is generated (missing counter account/mapping).

• A counter line is filtered out or becomes 0.00 due to rounding.

• An account is missing on a line, the line is ignored by Fortnox.

• An incorrect rule causes only the accounts receivable line or only the bank/expense line to be created.

Resolution

1. Ensure the voucher has at least two lines with non-zero amounts: one debit and one credit.

2. Specify the account on all lines.

3. Check the mapping so a counter account is always created for each event (payment, fee, rounding, etc.).

4. Adjust rounding so that total debit = total credit.

5. Run the event again once the voucher meets the requirements.

Example

Payment without fee (2 lines):

• Debit 1930 Bank: 1,000.00

• Credit 1510 Accounts Receivable: 1,000.00
