Since SBDH standardizes the way data is presented, the data elements within SBDH can
be easily located and leveraged by multiple applications. SBDH is a business document
header and should not be confused with a transport header. It is created before the trans-
port routing header is applied to the document and is retained after the transport header is
removed.
Although SBDH is not the transport header, data in it can be used by transport applica-
tions to determine the routing header since it does contain the sender, receiver, and docu-
ment details. It can also be used by business applications to determine the appropriate pro-
cess that is to be performed on the business document. The specifications are explained in
the following section.
