The user interface for confirming the purchase order from the supplier is opened via the desktop within the 'Classic' tab by clicking on the link located under 'PO Confirmation from vendor'.
The purchase order confirmation interface from the supplier is divided into three parts. On the left is a document preview, in the middle is a data entry area, and on the right is a toolbar with certain functionalities, depending on which tab is open. The data entry area is divided into four parts by tabs: 'Activity', 'Process Package', 'History' and 'All Tasks'.
