Mapping transport headers

Use the Graphical Data Mapping editor to transform transport headers.

When you create a top level graphical data map, only the Properties folder is initially included in the map, and a default transformation from input to output properties is created in a local map. You can then use the Message Assembly properties page in the Graphical Data Mapping editor to modify the transport headers and Local Environment that you might include in the map.

When a transport header is included in the map, only the fields that are mapped by transforms in the map are created in the output message assembly (which is propagated from the Mapping node).

Any transport header that is present in the input to the Mapping node, but which is not included in the map, is copied directly to the output message assembly that is propagated by the Mapping node. To modify any unmapped headers and folders, add the header or folder to the input and output assembly in the map, and provide transformations. To delete a header, add it to the input Message Assembly, but not the output. To create a header or folder, add it only to the output.

You can click the information icon on the input and output message assembly to view the mapped headers:

Screen capture that shows the Message Assembly window, in which the mapped headers are shown

Select the headers that you want to include in the map by clicking the Edit button for the Headers and Folders property on the Properties page, and then selecting the headers that you require. For example, select MQMD to include MQMD headers in the mapping:

Screen capture that shows the Add or Remove Headers and Folders window, in which you can select the headers you want to include in the map

For the output, you must select the parser to be used to create an MQRFH2 header: MQRFH2 or MQRFH2C:

Screen capture that shows the Add or Remove Headers and Folders window. In the MQ Headers folder, in the MQRFH2 header folder, MQRFH2C parser is selected

When you have included the headers, you can map them using the mapping transforms. For more information about the available transforms, see Transform types in the Graphical Data Mapping editor.
