The Structure Pane
The Structure tab shares a pane with the Data tab in the upper right section of Report Designer. The Structure pane shows the exact hierarchy of every element included in a report. If you add an element to the workspace, it will show up in the Structure pane; when selected there, all of its fine-grained details can be viewed and modified through the Style and Attributes panes in the bottom right section of the screen. In addition to the standard drag-and-drop method using the palette and the workspace, you can also add an element to a report by right-clicking on any of the report sections in the Structure list, then selecting Add Element from the context menu. You can delete any element in the list by clicking on it, then pressing the Delete key, or by right-clicking it and selecting Delete from the context menu.
Master Report or sub-report
This is the top-level category under which all other report bands are listed. For standalone or master reports, this will be Master Report; for subreports, it will be sub-report.
All of the elements shown in the page header band will be listed in this category.
All of the elements shown in the report header band will be listed in this category.
If you've created any groups for your report elements, they will show up here. You can add or delete a group by right-clicking the Groups heading, then selecting the appropriate action from the context menu. You can also delete a group by selecting it, then pressing the Delete key. Your Details band is considered a group, and is explained below.
All items you place in the Details band will appear in the Details heading under the Group section. There are also Details-specific Header and Body bands which are not displayed in the workspace by default, but are available in the Structure pane to add to. You can add these extra bands to your workspace by selecting each of them in the Structure pane, then clicking the checkbox next to hide-on-canvas in the Attributes pane.
In the event that your query does not return any data, whatever content you put into the No Data band will appear in your report. You can add a no data band to your workspace by selecting No Data Band in the Structure pane, then clicking the checkbox next to hide-on-canvas in the Attributes pane.

You can add a watermark to your report by clicking Watermark in the Structure pane, then either right-clicking it and adding an element directly through the Structure pane, or by clicking the checkbox next to hide-on-canvas in the Attributes pane and dragging an element to the new Watermark band.
