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.
This dialog box displays only if you use the Purchasing application.
You can access this dialog box while you are modifying an AP invoice with a workflow state set to start, in review, or in progress. You also need appropriate access rights to the AP invoice in order to modify the record.
If purchase orders are associated with an AP Invoice, the Project grid and Route To field are disabled.
