Inbound Processing Overview

This section describes the iWay business components and the processing steps in the basic inbound message flow.

The inbound process converts a TRADACOMS formatted document to an XML document. Inbound processing consists of the following components in the sample message flow:

• Inlet
  • The file listener picks up the incoming TRADACOMS document.
  • The preparser obtains the message type from the TRADACOMS document. The preparser converts the original TRADACOMS document to an XML representation of that document.

    The iWay Integration Solution for TRADACOMS supports one preparser, XDTRADPreParser (com.ibi.preparsers.XDTRADPreParser), which is provided by iWay Software.

• Validation

  The inbound TRADACOMS document is validated for structure and content. The published TRADACOMS standards and user implementation guides define element types (for example, numeric, alpha, or date) and describe business rules to apply for validation.

  For example, the following is a typical date segment in an inbound TRADACOMS document:

  FIL=7012+1758+160901+FL RLX'

  Note: All TRADACOMS dates use a six digit date format (YYMMDD).

• Route and Process Flow

  In our sample message flow, the validation report service (TRAD_Validation_rpt) creates a validation report in XML format. This report indicates success or failure transformation and contains the input and output documents. The route directs the document based on this report. You can also apply additional business logic by adding a service to the flow.

  For more information on the services available with iSM, see the iWay Service Manager Component Reference Guide.

• Outlet

  Outlets define how messages leave a channel at the end of a process. In this example, a Passthrough emitter is used. All the file emits are done in the process flow.

  For more information on the emitters available with iSM, see the iWay Service Manager User's Guide.
