A report is defined via a page template split into horizontal sections – bands. Each band is printed a different number of times depending on its function (the page header per page, the detail band per record).

Height rule

The sum of all band heights (except Background) must be ≤ page height minus top/bottom margin. The specified height is the minimum height – bands with text fields/subreports can stretch downwards.

The nine standard bands

Band	Purpose
Title	First visible band, created once; optionally on a separate page.
Page Header	Appears at the same position on every page.
Column Header	At the start of each detail column – typically column headings.
Group Header	Start of a group; can force a page/column break and be repeated.
Detail	Any number; repeated per record (unlimited total size).
Group Footer	Closes a group – e.g. subtotals, separator lines.
Column Footer	At the end of each column; not stretchable at runtime.
Page Footer	Page footer on every page with a header; not stretchable.
Last Page Footer	Different footer for the last page; ignored when height is 0.
Summary	Totals/averages at the end of the report (elsewhere „report footer“).
Background	Watermark/frame across the whole page; max. page height.

Adding detail bands

Add further detail bands via Add Another Detail Band. The order can be changed in the XML view: the <band> elements sit between <detail>…</detail>.
