Transfer orders using EDI ORDERS

Hello,

I am trying to use R47011 to generate ST/OT orders. I find on the oracle support that this functionnality is not possible, but in WS a field called SYPOBU allowed to enter the OT business unit.

Now this field doesn't exist and I think it is the only thing missing to use ORDERS to generate transfer orders.

Is there anyone on the community who has already made this possible?

Thank you.
