How to limit PO Re-approvals to user Defined Critical Items Only (P4310)

Trying to use PO Approval Routings, but avoid the requirement for reapproval of orders unless the quantity ordered or extended value changes.  Nonetheless, continue to have orders go back on hold for other changes, like changes in the delivery date.

 

On P4310 processing options, Tab 10 – Approvals, we have set

Option 1 (Route Code)  = 1, Route by Originator’s Address

Option 2 (Awaiting Approval Status) = 230

Option 3 (Approved Status) = 280

Option 4 (Reapprove Changed Lines) = 2 (User activated critical fields only)

Option 5 (Hold Code) = [blank] 

 

The Approval Critical Field were set using P43080 to be just 3 fields:

Extended Cost AEXP

Open Amoutn AOPN

Quantity Open UOPN

 

Despite this, orders go back to 230 status whenever anything is changed on an order line.
