It appears as though the customer order that you have was generated from a purchase order that was submitted from a connected company.  For example, Company A and Company B are sister companies and they order from each other and they are both using IFS.  When Company A places an order with B it is called an internal purchase direct that is “sent” through IFS.  The only way that your customer order can be changed is if the change is made on the original purchase order and then the change order request is “sent” to you through IFS.  That process will automatically update the customer order on your side.  This prevents you from altering the order on your side - causing a discrepancy on the PO side.

thank you for your quick response.

WE are using a package part when this issue occurs.

The Shipment type is NR and the Supply Code is “PKG” - when we modify the shipment type to NA we do not get this error - but we require the Shipment Type to be NR for this site.

ANy idea what I need to do to resolve this issue?

is the issue with the shipment or the Customer Order?

The customer order comes into a “corporate” site and then our process creates POs, DOP, Shop Orders, Customer Orders for the supply site and automatically creates a shipment for the customer order from the supply site, not the original customer order.

When doing interconnected (intersite type) orders, all of the changes have to originate on the beginning purchase order or customer order.  You can’t edit the final order without starting at the beginning.

From the error, it sounds like you are trying to make a quick change at the end, but there is typically an update flow that is dependent on all of the interconnects to get the end order to update.  I’ve spent many an hour untangling these sorts of messes when someone has done something out of order, there isn’t a one answer fits all sort of response, as much as I’ve tried to figure them out.  

I just know that always start at the beginning is the best practice, never at the end.
