The PO history transaction has three distinct areas of the screen display. Select the **folder icon** to open each section of the display. The best practice is to have the **Item Overview and Item Detail** sections open at all times.
- **Header** - Displays information from the requisition that is part of the header record. It is often blank but will contain comments or notes from Procurement and Supply Chain Management if applicable.
- **Item Overview** - Displays each line of the PO, including the item description, quantity, unit price, and, in some instances, the requisitioner and link to the requisition number.
- **Item Detail -** Features a drop-down menu where users can select each PO line and see detailed information, including the funding sources, invoice receipt, and associated goods receipt.
