Below are steps

PO  no 1 001 Created with Item X 1

PO Approved and sent to Supplier

But supplier  sent us new version of product - X2  as PO Product X1  is out of date ( old version)

( as it foreign  shipment we cannot return and we need to accept the new Proudct)

As  New Product X2  already  reached us  via  shipment.

Now what is best ODOO approach to handle  this  requirement,

IF we cancel PO- and create new PO- and we need have internal approval again- can we avoid  the approval process again
