i think you didn't read that i'm mentioned
in datatemplate
<parameters>
<parameter name="P_YOUR_PARAM" dataType = "number" defaultValue="0"></parameter>
</parameters>
<sqlStatement name="Q_DATA">
<![CDATA[
select &your_columns
from  &your_tables
where &your_where_clause
]]>
</sqlStatement>
</dataQuery>
<dataTrigger name="beforeReportTrigger" source="XX_YOUR_PKG.BeforeReport"/>
<dataStructure>
...in package
FUNCTION BeforeReport RETURN BOOLEAN IS
BEGIN
IF P_YOUR_PARAM = 'some_value' THEN
  your_columns := 'column1, column2';
  your_tables := 'table1, table2';
  your_where_clause := 'table1.id = table2.id';
ELSE
  your_columns := 'column3, column4';
  your_tables := 'table2, table3';
  your_where_clause := 'table2.id = table3.id';
END IF;
END;you can use another way - create your xml output by package like
fnd_file.put_line(fnd_file.output, '<ROWSET>');
fnd_file.put_line(fnd_file.output, '<ROW>');
fnd_file.put_line(fnd_file.output, '<DAT>' || some_value || '</DAT>');
fnd_file.put_line(fnd_file.output, '</ROW>');
fnd_file.put_line(fnd_file.output, '</ROWSET>');in package you can use all that you want
