Invoice exports are now blocked when the referenced project or work order is missing in the connected accounting system (Fortnox or Björn Lundén).
- Customer invoices are marked with "!Error project missing" in the External invoice number field when the project is missing.
- Supplier invoices are marked with "!Error import" in the External invoice number field and the message "Project/WO missing in Fortnox/BL" when the project or work order is missing.
- An email with details is sent to inform users when an export is blocked for this reason.
