Add Error Handling to the Business Process

Edit online

In this sample, shown in BPML, add error handling to the Sterling B2B Integrator business process you created that passes a document to the Connect:Direct Server Adapter (PNODE) which copies the file to the Sterling Connect:Direct® node (SNODE). The error handling ensures that the Sterling Connect:Direct session closes if an error is encountered during the session.

The onFault branch contains an instance of the CD Server End Session Service. If an error occurs after the Begin Session Service, the onFault logic is invoked and the End Session Service terminates the session with the Sterling Connect:Direct server.
