Composite and nested reports – PB Docs 125

Import does not support nested reports. If you attempt to
import data in any format, including XML, CSV, DBF, and TXT, that
contains a nested report, the nested report is not imported and
the import may fail with errors.

Composite reports

For composite reports that use the Composite presentation
style, the default template has elements that reference each of
its nested reports.

If a composite DataWindow contains two reports that have columns
with identical names, you must use the procedure that follows if
you want to generate an XML document with a DTD or schema. If you
do not follow the procedure, you will receive a parsing error such
as “Element ‘identical_column_name‘ has
already been declared.”

1. Create
   a template in the first report and select this template in the Use Template
   list on the Data Export property page.

2. Create a template in the second report.

3. If any element name is used in the template in the
   first report, change it to another name in the template in the second
   report.

4. Select the template for the second report in the
   Use Template list.

5. Generate the XML document.

These steps are necessary because you cannot use a given element
name more than once in a valid DTD or schema.

Nested reports

For report controls added to the detail band of a base report
that is related to the inserted report with retrieval arguments
or criteria, the report control is available to the export template
in two ways:

• Select an element in the template
  or add a new element, then select Add Child>DataWindow
  Control Reference. Any report controls inserted in the detail band
  are available for selection in the dialog box that displays.

• Drag a report control from the Control List view
  and drop it on an existing empty element.
