When the number of output objects is based on the number of some other object,
create a map rule that maps the output according to the number of occurrences of
an input.
Indexing an Output
When the number of objects to generate for each map execution is known, index
the number of occurrences of that output object. To index an output is to generate
a specific number of occurrences of that output.
Note The Use Ellipses option must be disabled when indexing. From the Tools menu,
choose Options > Rule Bar and disable the Use Ellipses check box.
To index an output
1 Right-click the output data object you want to index.
2 From the context menu, choose Add Index.
An output object is added to the output card. This output object has the index
number in square brackets. For example,
[1].
The index number identifies the occurrence of the object. The index number
[1]
indicates the first occurrence. The index number
[2] indicates the second
occurrence, and so on. After you have indexed an output, you can enter a map
rule for that indexed output. If you have indexed a group, you can then expand
the group and add map rules at the component level.
