You create partner profiles without default values from Customizing. Although this is the most individual way of maintaining partner profiles, it is also the most complex.
Partner profiles are defined separately for inbound and outbound processing. Every partner, however, must be defined in the general partner profiles. For outbound processing under Message Control (MC), you must also configure additional parameters. To define the partner profiles, go to the Initial Node of the IDoc Interface.
