The user interface for entering data of canceled accounts is opened by clicking on the 'Canceled' button on the toolbar or on the desktop within the 'Classic' tab by clicking on the link located under 'Canceled Accounts'.

The interface for processing canceled invoices is divided into a part with a document overview and a working part. The work section is divided into tabs and contains a toolbar with certain functionalities, depending on which tab is open.

The screen is divided into three parts. On the left is a document overview, in the middle is a data entry area, and on the right is a toolbar for a specific entry for processing incoming invoices.

The data entry area is divided into four parts by tabs: 'Activity', 'Process Package', 'History' and 'All Tasks'.
