Ax 2009_Purchase order status invoiced

Hello,

I have the possibility to delete a purchase order (PO) with the status invoiced. I would like to restrict this action. I had already search on the parameter ( AP/setup/ parameter) There is a checkbox which permit to delete a PO invoiced ( the action that i can do without select it…)

Never mind, do you know how to “not have the possibility to delete a PO invoice”

Note: when the status of the PO is received, it is not possible to delete.

Safety Level of Invoiced Order = Locked.
