I’ve got a WO to which I’ve tied a NO CO to the header and set the CO Type to NO on the task.

I have issued a part to the WO and I want to invoice the customer for that. 

I’m not seeing anything relating to Transfer to Customer Order.  Can you help here?  

I’ve tried using an SEO and I’ve tried to create the CO from the WO, which is does but still can’t see how to transfer this to CO.
