Defining Communication Parties
Use
A communication party (party for short) represents a larger unit, which is involved in a collaborative process. Using a communication party, you generally address a company within a business-to-business process.
You can assign a communication party one or more communication components to address it as the sender or receiver of messages.
You can specify alternative identifiers for the communication party so that communication party can be identified by using different, globally valid IDs.
