When the View Purchase Orders option is selected in the Customer Order Lookup, the system activates the All Purchase Orders for a Sales Order Lookup program and it loads the program with the open and closed purchase orders that have been placed for the selected sales order.
The All Purchase Orders for a Sales Order Lookup program displays the purchase order lines that have been created for the selected sales order (if any). The program displays the open purchase order lines linked to the selected sales order line in the top section and the closed purchase order lines linked to the selected sales order in the lower section of the program.
The All Purchase Orders for a Sales Order Lookup is part of the Purchasing (PO) system and it is completely described in the documentation for that system. You may access more information about the program by activating it and using the Help key to display the main help documentation for the program.
