In V5, how do I find a PO in the PO list, add a new PO, or export?

1. Find a PO: enter a keyword in the search box on the toolbar above the list (the default field is PO number) and press Enter; or click "Filter" to narrow the results with conditions. 2. View or edit an existing PO: click the PO number in the list to open that PO. 3. Add a new PO: click the purple "Add PO" button at the top right, fill in the PO information, and save. To create one from a file, click "Import" to its left. 4. Adjust displayed columns: click "Columns" at the top right of the list (for example, showing 9/14) and check the columns you want to display. 5. Export the list: click the download icon at the far right of the toolbar. 6. To change the number of rows per page, click "Preferences" at the bottom right of the list.
