I checked my invoicing control , it's based on quantity received, and the problem is still there, for example, PO display the quantity of item is totaly received, and even if I create the invoice based on the PO, after validation, the invoice appear on the accounting but in the PO windows it display 0 invoice !!

i'm using odoo 9 on windows.

That could be due to the Purchase Order was created using the manual method(Invoicing Control) that read as: "Based on Purchase Order lines"

That cause that the workflow object assosiated to the PO order gets the complete state without taking the invoice state subflow into account and the PO never get the state invoiced automatically when you are using that method
