About Maps
Maps define how data is transformed by the Integration
Appliance during run time. Maps can reorganize data, convert data,
suppress or add data, and performing calculations or other complex
conversions.
Creating a map
Create a map between the variables and the input parameter
or between the output parameters and the variables.
Creating a Standalone Map
A standalone map is visible in the Transformations folder
of the Project tab and represents a set of
one or more mappings between source and destination nodes.
Adding Variables to Mapping Panes
You can add existing variables to a map or create new variables
and add them to a map using the Select Inputs.. or Select
Outputs... buttons available from the mapping panes of
an activity.
About Unmapped Destination Nodes
During transformations, the Integration Appliance includes
all destination nodes in the result message. Destination nodes that
are not mapped become empty nodes in the resulting message.
Filter Recurring Nodes
By specifying an XPath predicate to filter against during
run time, you can limit the recurring nodes returned by a mapping
activity.
