Outbound Messages to Trading Partner with No Service Provider

There is no need to identify a recipient for outbound messages to trading partner.

In case of trading partner messaging (when no service provider is involved), there is no need to identify a recipient because the trading partner is the recipient. In such cases, the framework doesn't include additional protocol header fields. You can configure any fields needed by the trading partner on the channel definition in Oracle B2B.
