Customer Order Cancellation

you can shortly check the pool incoming change request in IFS, you need to approve the change 

Hi ​@sherry ,

First of all thanks for your responce.

When I checked the incoming change request for customer order page associated with the customer order no;
1-Status ---> Processed 
2-Changed item value--->Customer's PO No: prev value was xx, new value changed to null.

The relevant change appears to be  Processed, but the header status of the relevant customer order has not changed to canceled.

What could be the reason for this?
How can I change the header status of the relevant customer order to canceled without performing an additional cancellation process?

maybe you also need to shortly check following window, because the CO is generate by the PO.

just now i have play around in test system the process steps as following:

1 you need to send the change request from the PO

2 you go into the incoming change request for the customer orders, and approve the change request, then the CO will change to cancel directly.
