Introduction to Standard BizTalk Header Fields
BizTalk defines some standard XML elements for using with its envelope. The most important are:
*The <message> element with its sub-elements <messageID>, <sent>, <subject> can be used to identify a message.
*The <to> and <from> elements can be used to identify the sender and receiver in a communication process. Both may contain the sub-elements <address> and <state>.
*The <manifest> element can be used to describe the business documents delivered in the body.
A full BizTalk XML header may look like this (taken from the Microsoft BizTalk specification):
<?xml version='1.0' ?>
<biztalk_1 xmlns="urn:schemas-biztalk-org:BizTalk/biztalk-1.0.xml">
<header>
<delivery>
<message>
<messageID>xyzzy:8</messageID>
<sent>1999-01-02T19:00:01+02:00</sent>
<subject>Purchase Order</subject>
</message>
<to>
<address>http://www.fabrikam.com/recv.asp</address>
<state>
<referenceID/>
<handle/>
<process/>
</state>
</to>
<from>
<address>mailto:foo@contoso.com</address>
<state>
<referenceID>123</referenceID>
<handle>7</handle>
<process>myprocess</process>
</state>
</from>
</delivery>
<manifest>
<document>
<name>PO</name>
<description>Purchase Order</description>
</document>
</manifest>
</header>
<!-- body definition here -->
<biztalk_1>
For further details of the BizTalk XML envelope, refer to the BizTalk Framework 1.0a Independent Document Specification.
Adapter for SAP only uses a subset of these available header elements, which is described in the following chapters.
