So that you can receive messages in R/3 from external communications systems, create an RFC User. For each external communications system, create an RFC destination and a Node. You can add more systems, that is, create new nodes, even during operation. Since new Customizing settings may be necessary, you can branch directly from SAPconnect administration to Customizing (for example, to maintain the rules for recipient number adjustment).

Outgoing messages are first stored in a queue. So that the messages are sent from the queue to the external communications system, you must schedule send processes. You can divert incoming messages via inbound distribution using recipient addresses.

You can also change the default settings for confirmations of receipt in the Internet. You can specify a default domain to enable documents to be sent externally to users or objects to which no Internet address is assigned.

The tools for monitoring and for error analysis are available for monitoring sending. You can check the operating status of the external communication components in the R/3 System and evaluate the send status of the documents. If errors occur, you can set a trace that logs the processing of one or more messages.

An overview of the settings that you have to make in the R/3 System in order to enable sending can be found in the documentation on Sending in the R/3 System.
