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.

υInput Field. Specifies the name of the field on the Transport Dictionary from which the XML-formatted business data object is read.
υOutput 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`

Business data object. The data that appears between these tags represents an XML representation of the business data object written by the AddHeader component.	<`OBJECTDATA`> </`OBJECTDATA`>	Name/value pair specified as Output Field (default is `working`_`data`)

The message digest represents a hash of the business data object, and is not intended to be human readable. This data is sent back to the original sender by the GenerateReceipt component.
