Users often want the ability to customize a
report at runtime without having to actually modify the data model.
In Oracle
Reports, you can do this in one of
two ways:
- You can use lexicals (e.g., WHERE clauses)
or conditional logic.
- You can apply runtime customizations without
altering the base report definition (i.e., XML).
For example, suppose you are developing a report
that many users want to customize. When you update the report, the users
can simply reapply their XML customizations to it. If they didn't use
XML customizations, the users would have to manually update the report
definition every time you provided a new version of the report.
