A flexible subreport is a report definition specifically for mail merge reports and templates that are either in the .doc, .docx or .rtf formats. Contrary to a subreport, in which fixed descriptive text is typically listed above the values of the individual fields comprising the subreport, a flexible subreport allows you to combine fixed descriptive text and field values in the same paragraph. The field values and text for each element in the subreport (for example, for individual contract lines) are then listed consecutively in paragraphs.
