Create an inbound mapping service to map each element of the inbound RosettaNet PIP document to a corresponding data element in your internal system’s proprietary format. For example, if you use SAP R/3 as your internal ERP system, and you want to receive a RosettaNet PIP document from RosettaNet Module, you must create an inbound mapping service that maps each element of the RosettaNet PIP document to a corresponding element in the IDOC format.
