The inbound mapping service performs the reverse action of the outbound mapping service. In your inbound mapping service, map an RNO to the format used by your internal system.

The following figure illustrates an inbound mapping service from the PIP 3D8 Sample that handles large business documents.

The mapping service retrieves the payload from the BizDocEnvelope and then retrieves the non-repeating section. Then, it creates a document object and a node iterator from the payload stream. Next, it loops through each node and maps the node to the internal object.
