Create an outbound mapping service to translate a document generated by your internal system in proprietary format (for example, an IDOC from an SAP R/3 system) into a RosettaNet PIP document that you can send to your trading partners. Elements of the proprietary business document must be mapped to corresponding elements in a specific version of a RosettaNet PIP (for example, PIP 3A4 Request Purchase Order, version 1.1) document.
