The use of functional maps is very common. Almost every executable map created
uses at least one functional map.
For example, a functional map may be created to map one message to one row in
a database table. Alternatively, you might have a functional map that maps one
header and one detail to one item record.
Functional maps are used when an output component has a range of more than
one. For example, a range of (s) or (1:10). The number of output objects to be
created is based on the number of some input object. Functional maps are used to
transform data, mapping from one or more types to a different type.
Functional Map Wizard
The Functional Map Wizard in the Map Designer automatically creates a functional
map (or maps) based on a map rule. The maps that the Wizard creates contain
input and output cards, but do not contain map rules. Map rules for the objects on
the output card in the functional map must be created.
See the Map Designer Reference Guide for detailed information on maps,
functional maps, and the Functional Map Wizard.
Map Configuration
You configure how to run a map by:
♦ Specifying values for the settings in the Map Settings dialog box.
♦ Defining SourceRule settings on the input card.
♦ Defining TargetRule settings on the output card.
Map settings, input card settings, and output card settings may be overwritten at
run time. See Chapter 6 - Design and Execution for more information.
