You create an inbound mapping service to map each element of the inbound Chem eStandards payload to a corresponding element in your back‐end, proprietary business document format.

For example, if you use SAP R/3 as your back‐end ERP system, and you want to receive a Chem eStandards payload via the webMethods Chem eStandards Module, you create an inbound mapping service that maps each element of the Chem eStandards payload to a corresponding element in the IDOC format.
