To me this is not yet clear. Are you talking about the connection point of the sending side or is this the connection point of the receiving side (ie LN)?
I assume the LN connection point. On the details of the connection point the correct document needs to be switched on. Receive in Application field should be set to yes for the correct BOD, for example Process PlannedProductionOrder.
Is that the answer to your question? If not a picture could help to clarify your question.
