Pass-through support for IDocs, and MQSeries link for R/3 link migration

Both the inbound and outbound SAP adapters support a pass-through mode for IDocs.

In this mode, the bit stream for the IDoc is provided without any form of parsing. The bit stream can then be used directly in a message flow, and parsed by other parsers, or sent unchanged over transports.

Use the Adapter Connection wizard to select pass-through support: on the Configure settings for adapter pane, select ALE pass-through IDoc as the interface type.

A business object is created that contains one field, which is the bit stream of the IDoc. You can transform this business object in a Compute node to an MQSeries® link for R/3 format message, as shown in the following example.
DECLARE ns NAMESPACE 
'http://www.ibm.com/xmlns/prod/websphere/j2ca/sap/sapmatmas05';

CREATE COMPUTE MODULE test4_Compute
	CREATE FUNCTION Main() RETURNS BOOLEAN
	BEGIN
		CALL CopyMessageHeaders();
		-- CALL CopyEntireMessage();
		set OutputRoot.MQSAPH.SystemNumber = '00';
		set OutputRoot.BLOB.BLOB = 
InputRoot.DataObject.ns:SapMatmas05.IDocStreamData;
		RETURN TRUE;
	END;

	CREATE PROCEDURE CopyMessageHeaders() BEGIN
		DECLARE I INTEGER 1;
		DECLARE J INTEGER;
		SET J = CARDINALITY(InputRoot.*[]);
		WHILE I < J DO
			SET OutputRoot.*[I] = InputRoot.*[I];
			SET I = I + 1;
		END WHILE;
	END;

	CREATE PROCEDURE CopyEntireMessage() BEGIN
		SET OutputRoot = InputRoot;
	END;
END MODULE;
You can also create a request business object from an MQSeries link for R/3 message, as shown in the following example.
CREATE COMPUTE MODULE test4_Compute
	CREATE FUNCTION Main() RETURNS BOOLEAN
	BEGIN
		set 
OutputRoot.DataObject.ns:SapMatmas05.IDocStreamData = 
InputRoot.BLOB.BLOB;
		RETURN TRUE;
	END;
END MODULE;
The name of the SapMatmas05 element depends on selections that you make when you run the Adapter Connection wizard.
