Select Purchase Orders Dialog Box
Use this dialog box to select the purchase orders that are associated with the AP invoice while you are creating or modifying it.
You can access this dialog box if you are modifying an AP invoice with a workflow state of Start, In Review, or In Progress. Appropriate access rights to the AP invoice are also necessary to modify the record. The Purchase Order module is also needed to access this dialog box from the Purchase Order field. If purchase orders are associated with an AP Invoice, the Project grid and Route To field are disabled.
