Fedwire Enveloping Overview

A document envelope consists of control information that enables organizations to effectively exchange messages. This information is added to the Function Management Header (FMH). Document envelopes are specific to the message protocol used. Creating document envelopes is necessary to use Fedwire with your trading partners.

Fedwire has only one level of envelope, which you must modify appropriately to reflect your information and your trading partner's information. Envelopes specify whether the message is inbound or outbound:

• The Inbound Fedwire envelope identifies messages that are received by Sterling B2B Integrator so they can be properly routed. Inbound envelopes also give you the option to translate messages when you choose to check messages for compliance. By choosing to translate messages from within the envelope, you can reduce message processing time because you do not need to specify a separate Translation service step in the business process. You need to create an Inbound Fedwire envelope to configure deenveloping information.
• The Outbound Fedwire envelope identifies messages so that they can be sent to and received by trading partners. You need to configure an Outbound Fedwire envelope with the appropriate enveloping information.

When you envelope an outbound Fedwire message, the Fedwire Function Management Header (FMH) is created. For an inbound message, the envelope is looked up based on the Function Management Header (FMH) to determine the appropriate processing.
