PURCHASING > Purchase Orders > Modify a processed PO > Advanced (reloads PO into PO work area) > Abandon a PO modification (remove from work area)
This is used to remove a Change Order from your PO Work Area without processing it. Alternatively, you can also [DELETE] the Purchase Order from the PO Work Area Summary Screen.
The PO will be removed from the PO Work Area and unlocked throughout the system so that other/related transactions can once again be processed against the PO.
For additional details, see Advanced Purchase Order Modification.
