Fortnox error: 2002141

Description

Posting of the invoice was stopped because the accounting period is locked in Fortnox. When a period is locked, no journal entries/invoices can be posted with dates within that period.

Cause

• The invoice date (or posting date) falls within the locked period.

• The date is set by the integration (e.g., order/invoice date) to a closed period.

Resolution

1. Choose an open date: change the invoice date/posting date.

2. Unlock the period (requires permissions/administrator): temporarily unlock the period, post the invoice, then lock the period again. Do this only if it aligns with your procedures.

3. Review the integration settings: ensure that dates sent to Fortnox do not fall into a locked period (e.g., use “bookkeeping date = today” instead of the invoice date if policy allows).

4. If you lack permissions or are unsure—contact your Fortnox administrator/finance team.
