On the Composition tab of the Navigator, functional maps appear underneath
the executable map that calls it.
Entering Map Rules
The data objects on the LabelsOut output card on the F_MakeLabels functional
map need map rules to generate the output data.
A map rule defines how a particular data object is generated. Each component of
the #1 LabelsOut output card has a corresponding rule cell. In each rule cell, a
map rule defines how that output should be generated.
For example, the map rule entered for the FullName Field output data object
defines how the FullName Field data object is generated by the transformation
server.
Enter a map rule for each component of LabelsOut by starting with the simplest
map rule and then entering the more complex rules. Each map rule begins with an
equal sign.
