Click the Block/Unblock Open Creditor Items button to block an invoice for payment if payment should not be made yet. This may be the case, for example, if the invoice has not been approved yet or if you are not satisfied with the delivery. Once the invoice has been approved, click the Unblock button to release the invoice for payment.
Tip: You can block or unblock more than one invoice at a time (multiselect) by selecting multiple invoices and clicking the Block/Unblock Open Creditor Items button.
