There is no invoice with the reference number 'XXXX' posted to vendor 'XXXX' in division XX!
This error normally occurs when a payment has been exported but the linked invoice or invoices cannot be located in Sage.
Check in Sage for the invoice associated with the payment. If the invoice is missing you will need to re-export and re-sync that invoice.
If you have confirmed that the invoice is in your ERP, you may then proceed to re-export and sync the payment that is in sync error.
If you have carried out the steps above and are still having issues please contact Beanworks support at firstname.lastname@example.org.
