Sterling B2B Integrator Enveloping an EDI message Part 3 - Use a Business Process for immediate enveloping

In this step we will be implementing a BP that receives a valid EDIFACT message body and outputs the enveloped document in the Document Area after the EDIFACT Envelope step.

We are using this message as the input:

UCI+200905200086+SENDER+RECEIVER+7'
UCM+905201914+IFTMBC:D:99B:UN+4++FTX'
UCS+8+15'
UCM+905201915+IFTMBC:D:99B:UN+4++FTX'
UCS+8+7'

This is a typical CONTRL message without the enveloping fields.

This is the BPEL for the BP.

And the in GPM representation bellow, note that the EDI Encoder takes the Accepter Lookup Alias, and has the mode set gas Immediate.

In the first assigns we add some elements to override envelope settings with Sender and Recipient IDs, and the interchange number, check the BPEL.

Note that both the Correlation Service and the EDI Encoder are required steps for the enveloping process.

The resulting document can be handled in services after the EDIFACT Envelope, with services like File System Adapter or whatever it is required, you can also specify a BP to be trigger once the document is enveloped.

The BP output can be seen in the next screen with the enveloped message in document area, note the interchange number as it was specified in the BPEL and overridden at the envelope level.
