You may want to display additional data of a purchase order item in the worklist. For that, you click the purchase order number and item number to get the Purchase Order Details screen.

In the Purchase Order Details screen you can study the data of a complete purchase order, not only the data specific to the item you selected. To switch between the purchase order header and the purchase order items, choose Header or Item nn in the navigation bar. Expand the sections to display the data you want to study.
