You can export a data source schema that is used in a template
and modify it as necessary. Then, add the revised data source schema
back to the template by replacing the previous version with the new
version.
About this task
Changing the schema does not change the data that is used
in the generated report. Changing the schema affects only how
Rational® Publishing Engine uses
the data. You cannot edit with the
Schema discovery wizard,
export, or replace data source schemas that contain custom attributes.
Tip: When a data source schema has a root and a child node with
the same name, infinite recursion occurs. Infinite recursion is the
process of document generation that runs infinitely. Avoid issues
with infinite recursion by ensuring that all nodes have unique names.
