Hi @HoiIndikW 

I tested in 24R1 version and same behavior is observed. Therefore, as suggested in the previous post, similar steps need to be done as a workaround.

Since we are unbale to undo delivery of the customer order line coming from supply code service order, we will not be able to cancel the customer order line. Therefore, as a workaround the following can be done.

1. Click on the “New Credit Lines” button from the invoice preview and approve it (this will create two new sales lines -1 and +1 in conclude work order sale tab). A new customer order will be created as minus value of the initial Customer order.
2. Go to the created customer order and process it until invoiced/closed. Now the total impact of the previous customer order line is reversed.
3. If you go to the conclude work order, you will see that two lines have been created in respect with the credit invoice created from the invoice preview. First line is created with minus value and a customer order is already connected. Once that customer order is invoiced/closed. The total impact of the previous CO line is reversed.
4. Second line is created by the system, in case you want to do some additional invoicing to customer. If you do not want this line, you can remove the line from the conclude work order.

Hope this helps.
