You design a process model that involves EDI documents in the same way that you would form any process model. For more information, see the webMethods BPM Process Development Help for your release.

Sample process models that involve EDI documents are provided in the Knowledge Center on the Empower Product Support website at https://empower.softwareag.com. You can import and view the sample models in Designer.

Business processes that involve EDI documents typically only involve the Transaction document and the level of the document for the functional acknowledgment (that is, a Group document for ANSI X12 and an Interchange document for UN/EDIFACT).

When you define the process model, the first step always involves waiting for a document. You assign an input subscription to that step to specify the type of document for which to wait. You identify the document by its TN document type. You can set criteria for the start document so that the process begins only if the document contains specific information. For example, you can set criteria so that the process starts only if the sender of the start document is a specific partner. You set the criteria by assigning a subscribe filter to the start step.

At run time, when the document arrives, the business process begins.
