You can create as many mappings as required, one mapping for each message structure for which you want to process the interface files to the backend system.

When you create the mapping you select the

B2B Gateway

document store as the source, select the fields that you want to use in the mapping, and define the sample interface files of the structure as source parameters. You configure the organization backend system as the mapping target and map fields. You can add other elements to the mapping, based on your business logic, for example, filters and joiners.

To define the

B2B Gateway

document store as a source, you select a flat file connection that accesses the interface files. You must parameterize the connection. You can add as many connections to interface files as required.

Optionally, you can add more sources to the mapping. You can use any Informatica connection that isn't a

B2B Gateway

connection. Do not parameterize the connections.

After you add all the required elements to the mapping save and validate the mapping.
