You block the items that, regardless of their due date, you do not want to pay. To do this, you enter a blocking key in the item that represents the reason for blocking. If you want to block the account of a customer or vendor from payment, you enter the blocking key in their master record.
The standard system contains several blocking keys, which you can add to or change.
The payment program creates a payment proposal during the payment run. The payment is made on the basis of this payment proposal list. The blocked items are displayed separately in the list. You can process the payment proposal, and, for example, set or cancel the payment block on an item.
It is also possible to specify that a blocking key cannot be changed from the payment proposal transaction.
