BizTalk ESB (Enterprise Serivce Bus) – Interview of Neal Walters and Yogi Veda

An Itinerary would be a sort of a travel plan for the message based on the current information the message can provide to the Itinerary processor. There can be two types of itineraries Predetermined and Dynamic. Predetermined is when the steps are always the same for a business process. Where as with the dynamic itinerary the outcome of a preceeding step might determine what the next step will be.

In our case, we built the itineraries using BizTalk’s business rule engine. The header message in our common cannonical message contains the entire itinerary, along with information about the current step. Data from the message can be used to determine what the next step should be.
