To perform EDI de-enveloping, transformation, and validation or to make transformations between ROD, XML, and EDI, you need to import the associated maps from the Data Interchange Services client. Data Interchange Services is a separately installed program that typically resides on a different computer from the one on which WebSphere Partner Gateway runs.
The Data Interchange Services mapping specialist creates maps describing how specific documents should be transformed and validated. For example, you might have a purchase order created by a back-end application that you want transformed and sent to a community participant as a standard EDI X12 purchase order (850). The Data Interchange Services mapping specialist would write a map detailing how to transform each field or piece of data from your program to the X12 format. The map would then be exported directly to WebSphere Partner Gateway, or it would be exported to a file, which you would then import using a command script.
Detailed information about how to import maps from the Data Interchange Services client is provided in Importing maps.
