When you receive EDI and EDIFACT messages from partners, the pre-packaged, EDI processing mappings validate the inbound messages and convert them to XML interface files, one file for each message type.

To send messages to partners, you create interface files and place them on

B2B Gateway

. You create an interface file for each type of message that you send to partners. The gateway creates a valid EDI message file for each interface file and sends the message files to the partners.

The structure and elements of an interface file reflect the structure and elements of the relevant EDI X12 or EDIFACT standard for the specific message type. For example:

The pre-packaged schemas for

B2B Gateway

can be loaded into

Data Integration

during organization provisioning, or any time after provisioning. The pre-packaged schemas are used in the Hierarchy Parser and the Hierarchy Builder transformations to define the expected structure of an inbound or outbound interface file. Each message type and version has its own schema. Before you create an interface file, study the schema for the message type so that you structure the hierarchy correctly.
