To create a custom transport attributes definition

1. In Enterprise Designer with the Project Explorer tab active, in the project tree, right-click the project or subproject where the transport attributes definition will reside.

2. On the context menu, point to New, and click B2B Transport Attributes Definition.

   The project tree displays the new component, and a properties dialog allows you to edit the attribute definitions. See Figure 4–4. It is good practice to rename it from B2BTransportAttributesDefinition n to a meaningful short name beginning with tad to indicate that the component is a Transport Attributes Definition.

   This new component is useful only by virtue of its configuration — you need to add and define attributes that govern the nodes in the OTD that are generated from it. Once attributes are defined, they can be exposed to eXchange Partner Manager (ePM) for delivery channel configuration.
