Hi CRM experts,
We are about to use ECC advanced return order for a new process (ECC EHP 4)
we'd like to display and create this ECC advanced return order in CRM web UI with LORD API. We already use LORD to create and search standard sales order in web UI (CRM EHP1).
I made some tests and I can display an ECC advanced return order but the thing is that data from "Return" tab at item level is not available in ERP UI component. This is the tab which makes the difference with the classic return order 
Do you know if I have to activate any business function or sicf service to get this "return" tab available in ERP UI item component (ERP_I) ?
Thank you all in advance for your help.
Regards,
Pierre
