I have a doubt regarding XI parties. I understand that party is used when we are exchanging messages in a cross-business scenario (B2B). In my case, Im talking about an IDoc scenario in a A2A vision, or either, all the Business systems involved are into our landscape, however, in the technical design, some of them have the profile type KU (customer), and all the documentation that I read (SDN) mention the usage of Parties for that kind of Partner Profile.
Tell me if Im right, LS means ALE and KU means EDI and EDI is for B2B scenarios So, Do I need to define a Party or I can skip it and use this profile type with services without Party?
Thanks in advance,
