By pressing F3 you are presented with a list of people who are able to Approve based on the People Master Files. Make your selection and Close the door. This will assign the PO to that Logged in User and the Approved By title will highlight red.

Note: that there is an assumption that if a user is a PO Approver that they will also have the Admin Function Approve Purchase Order.

You may not have rights to the Approved By dropdown because you don't have the appropriate Admin Function but you can still access the F3 Popup because you are assigning it to somebody else to approve.

Whoever is logged in at the time of approval will have their PersonID attached to the Purchase Order Header on the table.
