A message map can be
used by one or more Mapping nodes
in a message flow. You can reference
a message map by configuring the Mapping
routine in a Mapping node.
About this task
The Mapping node
invokes a map-based transform.
The input to the Mapping node is the input
message assembly that is propagated from the upstream node.
The
output of the Mapping node
is the new message assembly that is created by the mapping operations
and propagated from the output terminal of the Mapping node.
Procedure
To reference an existing message map from a Mapping node, complete
the following steps:
- In the Application Development view,
double-click the message flow that
contains the Mapping node
that you want to modify.
The message flow opens in the Message
Flow editor.
- In the Message
Flow editor,
click the Mapping node
that you want to modify.
The Mapping node properties
are displayed in the Properties view.
- In the Properties view, select the Basic tab.
- Next to the Mapping routine field,
click Browse.
The Data
Transformation Map Selection window opens.
- From the list in the Data Transformation Map
Selection window, select the message map that you want to reference
from your selected Mapping node,
and click OK.
Message maps are listed in the format {BrokerSchemaName}:MapName.
{default} indicates
that no broker schema is used by
the message map.
- Save and close your message flow.
Results
Your Mapping node
references the message map that
you selected.
