I believe there is nothing called 'Canceled Purchase Invoices'
I have never seen any way to cancel a 'PO Invoice'
yes, for PO Receipt you can cancel and correct it as well.
all I know, If you get some issue, with posted po invoice, you can set a credit note or you can make correction in it. there is no button to cancel a PO invoice
can you show us how you are canceling invoices in standard AX.??? or you have some customized process here.???
