Hi @ERPMark1,
In IFS you can define authorization for purchase requisition and purchase orders separately and there is no such functionality in place not to request authorization for purchase order if the requisitions are authorized this might be due to the fact that you can connect multiple requisition lines to one PO and vice verse.
If you don't want PO authorization, then don't define any purchase order authorization rule and uncheck the enforce purchase order authorization at company, then system wont ask to authorize the purchase order.
In your case, system is asking for authorization of purchase order because you might have define the purchase order authorization rule for the site. You can change the status of purchase order authorization rule to planned and then you can release PO without authorization
Hope this helps!!
