Hi,
I have just created ER 113701 to add an api transaction to be able to copy a customer order line. If you are interested in this functionality, please register your vote here : https://mingle-portal.us2.prd3.inforcloudsuite.com/v2/CONCIERGE_PRD/?LogicalId=lid://infor.cxp.1&Tab=ERS&ERId=113701
Thanks
You can always create a IPS API to allow you to handle the Copy.
