The BTS Transport Layer
This layer monitors the transportation of the BizTalk documents and interchanges using the InterChangeRcvd test and InterChangeXmit test shown in Figure 1. A business document is an XML document containing the business transaction data. This transaction data may represent a purchase order, invoice, sales forecast, or any other business information. A BizTalk document is a combination of one or more business documents, and zero or more binary file(s). BizTalk interchanges refer to a collection of one or more document instances that comprises a single transmission. This is exchanged from application to application within an organization or from one trading partner to another.
