The buyer should check whether the price variance in an invoice item is justified. The buyer can make use of the following environment information for the invoice items: invoice, purchase order, and memos.

• Release invoice item
• Flag invoice item as cannot be clarified

The event for the change document PurchaseOrder.changed must be triggered for the purchase order (BUS2012) so that you can change a purchase order.

The buyer can change the relevant purchase order for selected invoice items blocked for price reasons. If all the purchase orders have been changed, the system checks if the price blocks in the invoice items have become invalid due to the change in the order prices.

If there are still price blocks that need to be clarified, the buyer can process the work item again.
