Setup Outgoing AIF Port for a Customer in AX2012 (SalesInvoice)

In AX2012 R3 CU11, Going to setup an Outbound Port for sending EDI invoices to Customers. In AX2009 there was an option on the Endport – „Constraint“ where you can specify Customer this port is active. In AX2012 this has changed, and Outbound and Inbound ports are more “Document” related. but in my search for a solution is only see answers like “Legal entity” - but this is our “companies” and not our trading Partners!

Any expericence ?

I’m locking this thread, because there is already one for the same question: AIF Configure Outbound Port missing Constraint.

If you have any reply, please put it there.
