Mapping node

The Mapping node has one or more mappings that are stored in message map files (with a .msgmap file extension). These files are configured using the Message Mapping editor.

A Mapping node must contain the following inputs and outputs: You must define, in message definition files in a message set, the source and target messages that are to be mapped. You can specify the parser of the source message at run time (for example, in an MQRFH2 header), but the target message is built using the runtime parser that is specified by the Message Domain property of the message set.

If a message mapping is between elements of different types, you might need to include casts in your mapping definitions, depending on which runtime parser is specified by the Message Domain property of your message set.

The Mapping node uses a language to manipulate messages that are based on XPath.

To develop message mappings for a Mapping node, use the Message Mapping editor, which provides separate panes for working with sources, targets and expressions.
