OpenHeader

OpenHeader

The OpenHeader component, which usually appears in the Open Header Stage of a Commerce Interchange Receive pipeline, reads the XML header tags appended to the data object by the transmit pipeline's AddHeader component, and writes the XML-mapped business object, the transaction ID, the data and time of the transmission, a message digest, and other optional values to the Transport Dictionary as name/value pairs.

Input Field. Specifies the name of the field on the Transport Dictionary from which the XML-formatted business data object is read.
Output Field. Specifies the name of the field on the Transport Dictionary to which the business data object is written.

The following table lists the XML values that are written as name/value pairs by the OpenHeader component.

Purpose	XML Tag read	Name/Value written
Return receipt information. Optional. This information is needed by the GenerateReceipt component later in the pipeline.	`<RETURNREQUEST> <DIGESTALGORITHM> algorithm </DIGESTALGORITHM> <DOCUMENTTYPE> requestedDocumentType` `</DOCUMENTTYPE> </RETURNREQUEST>`	`return_receipt_request`
Message digest. Optional. A digest of the business data object.	None.	`msg_digest`.
Transaction ID. Unique identifier of the business transaction.	<`TRANSACTIONID`> </`TRANSACTIONID`>	`txid`
Document type. Optional. Description of the type of business object being transmitted	`<DOCUMENTTYPE> </DOCUMENTTYPE>`	`Document_Type`
