This error message occurs when exporting to AFAS if it was not possible to add an attachment to the sales transaction.
Are you working with AFAS Small Business?
In AFAS Small Business it is not possible to send transaction documents for sales transactions.
Solution: remove the 'Sales dossier item type' in the company settings. Go to Manage / Organisation / Companies, click 'Edit' and go to the tab 'AFAS'. When the number in 'Sales subject item type' is removed, transactions can still be exported without an attachment. The transaction document and attachments will of course remain available in the Zenvoices archive.
