Communication in SAP XI is interface based. There are two types of interfaces:
Outside-in: You create the relevant interfaces from the Oracle system in the integration builder.
Inside-out: The functions that are to be called using SAP XI already exist in Oracle. This requires using the integration builder in XI.
You configure the cross-system Oracle to SAP processes for an existing system landscape. The configuration describes how the integration server is to process inbound messages and to which receiver or receivers messages are sent. Various engines are involved in message processing on the integration server.
