Composite and nested reports
Report controls can be referenced in the Detail section of
export templates as children of an element.
Nested reports supported for XML export only
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.”
-
Create a template in the first report and select this
template in the Use Template list on the Data Export property
page. -
Create a template in the second report.
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. -
Select the template for the second report in the Use
Template list. -
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.
When you export XML using a template that has a reference to a
report control, the export template assigned to the nested report with
the Use Template property is used, if it exists, to expand the XML for
the nested report. If no template is specified for the nested report,
the default template is used.
The relationship between the nested report and the base report,
for example a Master/Detail relationship, is reflected in the exported
XML.
